How full text search is working in Alfresco?

Jump to solution

I have following text  "Brown fox can do" in one of the file uploaded in alfresco.

When I am trying to search using AFTS using following query and I am getting the document in results every time.

TEXT:"do" 

TEXT:"doing"

TEXT:"doed" 

I want to understand how full text search works in Alfresco ?

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".

Thanks Jeff. I got to know the same when I was going through the Solr documentation.

I am finding out how can I disable it and potential impact of it on the system.
