Alfresco uses Solr. The behavior you are seeing is functionality common to most search engines--not just Solr--called stemming. All three of your searches get analyzed by the search engine and those terms get "stemmed" to the their root. In this case, the stem is the same in all three cases: "do". That's why the document shows up for all three searches. For more info, search the internet for "Solr stemming".
