Re: Search schema using q Query

[dabboo <ag...@sapient.com>]

Hi Hoss,

Thanks a lot for the information. Here is what I am trying to achieve.

1. I am trying to customize the search with q query parameter, so that it
can support wildcard and field boosting. I customize QueryParser and created
the wildcard query in the same way as it does for non wildcard. But even
with this changed query, the results are not showing up. 

I figured out as how it is doing the field boosting with the scores. But
what I want to know is how it is fetching the records from the indexes based
on the query.

Please suggest how I should go forward.

Thanks,
Amit Garg

I don't see how anyone could possibly make any suggestions about 
where you should go from here, since you haven't provided any detials 
about what it is you've done --- you said you've customized the 
QueryParser, but without giving us any idea of *how* you've customized the 
query parser, no one on this list is in any sort of position to guess what 
your problem might be.

there are people on this list who clearly want to help you, but you have 
to help them by giving them *all* of the information relevant to your 
problem.  

What *exactly* did you change?  what does your code look like?  what do 
you configs look like? what data have you indexed? what do your query URLs 
look like? what results do you get? what results do you expect to get?
