This is called 'stemming', and is caused by this:
<filter class="solr.SnowballPorterFilterFactory"
language="English"/>
It means that all of these terms would match:
behave
behaving
behaved
(and possibly more)
because they would all stem down to 'behav'.
This stemming will happen at index time and at query time, so stemmed
terms are stored in your index, and also, as you are seeing, stemming
happens on your query terms. You can use the 'analyze' option in the
admin interface to see what happens to terms at query/indexing time for
your various field definitions.
