Disable Full Text Indexing

jjf

Is there a way to disable full text indexing of content? If so, will this aid in the performance of running "index.recovery.mode=FULL". Right now a full index takes hours to run and over 1GB of memory. We have no need for Full text indexing in Alfresco so if it can be disabled, we'd like to pursue that. Thanks.

Same problem. Any suggestion is greatly appreciated.

I'm not entirely sure if it will work, but you could try setting:
lucene.indexer.maxFieldLength=0
in custom-repository.properties

Also- if you use versioning I would highly recommend you use, at least, 2.1.6 since it speeds up a full index rebuild a lot.

derek

Hi,
Full text indexing is not the problem since this is done in the background anyway. The problem is index rebuilding.
msporled is quite right: 2.1 SP6 improves the index rebuild speed significantly by batch-processing transactions using a thread pool. If you are running the community edition, then you could upgrade to Labs 3b to get the faster, multithreaded version of the rebuild.

jjf

What about changing the lucene.indexer.maxFieldLength field as suggested above? Will that improve performance?

You should be able to override the definition of the luceneIndexerAndSearcher to pass it a custom ContentService (proxying the "original" one) that'll always return a "null" ContentReader: if Alfresco cannot read a document's content, it won't be able to index it.

derek

Hi,
As I said before, disabling full text indexing will not be a magic bullet. Stick a profiler against the system, if you wish. The fundamental issue is that the full text indexing was single-threaded.
Regards

jjf

If it's not full text indexing that's causing the issue then I guess the question is what is taking up memory and time when it does an index rebuild? And is there anyway to tweak the system to improve the memory usage and rebuild time? We've tried tweaking the lucene settings in repository.properties but that hasn't shown any benefits.

Is upgrading to 2.1Sp6/labs3b the only option?

msporled

Is upgrading to 2.1Sp6/labs3b the only option?

Upgrading to 2.1.6 took our rebuild from hours to minutes. (or from days to hours, depending on how much data we had and the size of the box)

I'm using 3.1sp1 and have noticed that there IS a problem indexing large excel files (300+meg). During indexing, our system grinds to a halt and we can experience oom issues.

I've profile the app and Alfresco uses POI to open and index these files. This takes upwards of 1g+ in memory whilst indexing. When finished indexing, the memory is released and the system goes back to normal.

We would like to disable indexing of content for only one of our content types.

Can we override the cm:content indexing property in our custom property?

If not, how can we get around this?

Thanks for any help!

derek

Hi, Lee

You can disable the POI transformer and the slack will be picked up by the OpenOffice transformer; POI is much faster but has the drawback that it keeps the document in memory during the transformation. Contact our support dept. if you have any trouble.

I'm using 3.1sp1 and have noticed that there IS a problem indexing large excel files (300+meg).

Maybe try a File, Save As to see if you can reduce the file size. To me 300+meg seems a bit like the file has phantom size added.
Have a look at http://www.ozgrid.com/Excel/ExcelProblems.htm or http://www.brainbell.com/tutorials/ms-office/excel/Reduce_Workbook_Bloat.htm or try searching internet for "excel large file size". Quite a lot of hits.

Isn't really an answer to your issue, but might be worth looking into.

lee

Hi Loftux,

Thanks for the suggestion.
Unfortunately our excel files really are that large.

For now, I've disabled the poi transformer as Derek suggested and that has worked. Obviously a better solution might be to use the low-level event oriented poi api when indexing. This would both speed up the indexing and keep mem usage low. If I get around to doing this, I'll post the code for all.

Thanks for your help

zladuric

I'm pretty new at all this so I may ask a newbie question now:

will disabling indexing of content also disable the indexing of metadata?

All my content are just docs scanned to pdf, I really have no use of these being indexed (my users, that is).

TIA,

Zlatko

derek

Hi,
You can switch the indexing of content off by modifying the cm:content property in the model and the other metadata will still be indexed.
Regards

zladuric

Can I bother you a bit more on this?

What model do I need to modify? My own or some predefined one?
And modify it in what manner?

lee

What model do I need to modify? My own or some predefined one?
And modify it in what manner?

You need to modify the default content model which should be called contentModel and found under WEB-INF/classes/alfresco/model.

You could change the cm:content type definition to something like this:

<type name="cm:content">
         <title>Content</title>
         <parent>cm:cmobject</parent>
         <archive>true</archive>
         <properties>
            <property name="cm:content">
               <type>d:content</type>
               <mandatory>false</mandatory>
               <!— Index content in the background –>
               <!– THIS DISABLES INDEXING–>
               <index enabled="false">
                  <atomic>true</atomic>
                  <stored>false</stored>
                  <tokenised>true</tokenised>
               </index>
            </property>
         </properties>
      </type>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Beware that this turns off indexing for all cm:content nodes. It's possible this may have unintended consequences elsewhere as there may be other processes that require the content to be indexed in order to work correctly (though the alfresco guys would have a better idea of this). For example, you may have more trouble using the search box - in that you won't get results you expect.

It's probably best to only turn off indexing for the specific content types you want. You can override the cm:content property for a specific type in your custom model. See this blog for help: http://www.ixxus.com/blog/2009/01/aspects/

zladuric

Would that be posible in my custom model like this?

[… model definition etc…]
<type name="protenus

okumentDefault">
      <title>Default dokument</title>
      <parent>cm:content</parent>
      <properties>
         <overrides>
                   <property name="cm:content">
            <type>d:content</type>
            <mandatory>false</mandatory>
            <!— Index content in the background –>
                          <index enabled="false">
                         <atomic>true</atomic>
                         <stored>false</stored>
                           <tokenised>true</tokenised>
                      </index>
                   </property>
         </overrides>
         <property name=…
[… and so on, my custom properties…]

index enabled is true in contentModel.xml, I've put it to false here. Will that disable my properties being indexed or just the content?

TIA,

Zlatko

lee

That disables the indexing of cm:content for content type protenus

okumentDefault only.

zladuric

Yes, in our custom model. The docs usually enter our system by being scanned to pdf and assigned one of the protenus: types. If anything else gets in the system, it's gonna be fine.

However, I still have some problems. I just came to a co that uses Alfresco (comunity, 3.0). I copied over the database and the contentstore AND the whole tomcat directory, but I can't seem to get alfresco to work on my machine with that. When I point it to empty contentstore and empty database, it starts and it's all great, /alfresco app is working and all is well. However, when I use the existing data, I have to rebuild the index (for some 100k transactions) but I always get an OOM.

and it goes on like that.

I wonder if you know how would I get it to start and work on my devel box?

Btw, both machines have 64 bit Sun Java and all is the same, except that the production box has 4 gigs of RAM and I have 2gigs..

lee

Check the forums for oom errors there are a lot of posts regarding how to deal with them. You may also want to look at the documentation for how to backup alfresco correctly instead of just copying everything across.

This will get you started with jvm tuning: http://wiki.alfresco.com/wiki/Repository_Hardware

zladuric

I did, I've done a lot of tuning, but I can't get a hold of what's wrong. I just want this indexing part to finish, then I'd be on my way.

Anyway, thanks for your help.

Apparently override indexing is impossible.
In modelSchema.xsd index tags don't exist in propertyOverride.

http://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/config/alfresco/model/modelSchema.xsd :

….
   <xs:complexType name="propertyOverride">
      <xs:sequence>
         <xs:element name="mandatory" type="xs:boolean"
            maxOccurs="1" minOccurs="0" />
         <xs:element name="default" type="xs:string"
            maxOccurs="1" minOccurs="0" />
         <xs:element name="constraints" maxOccurs="1"
            minOccurs="0">
            <xs:complexType>
               <xs:sequence>
                  <xs:element name="constraint" type="dd:constraint"
                     maxOccurs="unbounded" minOccurs="1" />
               </xs:sequence>
            </xs:complexType>
         </xs:element>
      </xs:sequence>
      <xs:attributeGroup ref="dd:name" />
   </xs:complexType>

Only mandatory, default and constraint can be override.

HI,
from Alfresco 4.0.d on it is possible to control indexing on a particular content type exploiting the cm:indexControl aspect, provided with basic contentModel.xml:

<!–                  –>
      <!– Indexing control –>
      <!–                  –>
      
      <aspect name="cm:indexControl">
         <title>Index Control</title>
         <properties>
            <property name="cm:isIndexed">
               <title>Is indexed</title>
               <type>d:boolean</type>
               <default>true</default>
            </property>
            <property name="cm:isContentIndexed">
               <title>Is content indexed</title>
               <type>d:boolean</type>
               <default>true</default>
            </property>
         </properties>
      </aspect>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hope this helps.

Andrea
