This is a stemming artifact, that all of the forms of evaluat* are being
stemmed to "evalu". That may seem odd, but stemming/stemmers are odd to
begin with.
1. You could choose a different stemmer.
2. You could add synonyms to map various forms of the word to the desired
form, such as eval.
3. Accept that Solr ain't perfect or optimal for every fine detail.
4. Or, maybe the stemmer behavior is technically "perfect", but perfection
can be subjective.
In this particular case, maybe you might consider a synonym rule such as
"eval=>evaluate".

Subject: question on word parsing control
I have a field that is defined using what I believe is fairly standard
"text"
fieldType. I have documents with the words 'evaluate', 'evaluating',
'evaluation' in them. When I search on the whole word, obviously it works,
if I search on 'eval' it finds nothing. However for some reason if I search
on 'evalu' it finds all the matches. Is that an indexing setting or query
setting that will tokenize 'evalu' but not 'eval' and how do I get 'eval' to
be a match?
Thanks,
Ken
