One word phrase search to avoid stemming in Solr

I have stemming enabled in my Solr instance, I had assumed that in order to perform an exact word search without disabling stemming, it would be as simple as putting the word into quotes. This however does not app开发者_开发百科ear to be the case?

Is there a simple way to achieve this?

There is a simple way, if what you're referring to is the "slop" (required similarity) as part of a fuzzy search (see the Lucene Query Syntax here).

For example, if I perform this search:

 q=field_name:determine

I see results that contain "determine", "determining", "determined", etc.. If I then modify the query like so:

 q=field_name:determine~1

I only see results that contain the word "determine". This is because I'm specifying a required similarity of 1, which means "exact match". I can specify this value anywhere from 0 to 1.

Another thing you can do is index the same text without stemming in one field, and with stemming in another. Boost the non-stemmed field & that should prefer exact versions of words to stemmed versions. Of course you could also write your own query parser that directs quoted phrases to the non-stemmed field only.
