Solr Search in stemmed and non stemmed mode
Hi !!
I'm looking for a way to have two index in solr one stemmed and another non
stemmed. Why ? It's simple :-)
My users can do query for :
- banking marketing => it return all document matches bank*** and
market***
- "banking" marketing => it return all document matches "banking" and
market***
The second request need that I can switch between stemmed and not stemmed
when the user write the keyword with quotes.
The optimal solution is : solr can mix gracefully results from stemmed and
non stemmed index, with a good score calculation ect...
The near optimal solution is : if solr see " " it switch in non stemmed mod
for all key words in query
I have an idea but I prefer to listen the comunity voice before to propose
it. I'll expose it in my next post.
If someone has an graceful idea to do this craps :-)
Thanks

Short answer: the standard query handler is right for carefully
designing queries. The dismax query handler is right for putting a
'search box' in a web page for regular users.

Thanks,
I'll read the mail archive.
Your suggestion is like mine but whitout the DisMax handler. I'm going to
read what is this handler.
I have one field text and another text_unstemmed where I copy all others
fields. I'm writing my custom query handler who check if quotes exists and
switch between the good field.
Going to read...
Thanks

Try searching the mail archive for
stemmer exact match
or similar, this has been discussed multiple times and you'll get more
complete discussions waaaay faster....
One suggestion is to use two fields, one for the stemmed version
and one for the original, then use whichever field you need to via
DixMax handler (more detail in the mail archive).
