Wildcard search not working if full word is queried
Hi everyone,
I'm having some trouble figuring out why a query with an exact word
followed by the * wildcard, eg. teste*, returns no results while a
query for test* returns results that have the word "teste" in them.
I've created a couple of pasties:
Exact word with wildcard : http://pastebin.com/n9SMNsH0
Similar word: http://pastebin.com/jQ56Ww6b
Parameters other than title, description and content have no effect
other than filtering out unwanted results. In a two of the four
results, the title has the complete word "teste". On the other two,
the word appears in the other fields.
Does anyone have any insights about what I'm doing wrong?
Thanks in advance.
Regards,
Celso

You are very welcome and yes I should have mentioned that wildcard searches are not analyzed (which is a recurring theme). This also means that they are not downcased, so the search TEST* will probably not find anything either in your set up.
Cheers

Hi again,
read (past tense) TFM :-) and:
"On wildcard and fuzzy searches, no text analysis is performed on the
search word."
Thanks a lot François!

Hi François,
it is indeed being stemmed, thanks a lot for the heads up. It appears
that stemming is also configured for the query so it should work just
the same, no?
Thanks again.

I would run that word through the analyzer, I suspect that the word 'teste' is being stemmed to 'test' in the index, at least that is the first place I would check.
