RE: Modifying fl in QParser

[Beale, Jim (US-KOP)]

All,

Thank you all for your responses.

Our custom QParser identifies several of many dynamic fields for construction 
of the actual Lucene query.  

For instance, given a custom Solr request consisting of 
"q={!xyzQP}scid:500247", a new query is to be constructed using information 
from a SQL query which selects certain dynamic fields, e.g. p_001, q_004, r_007 
along the lines of "+p_001:abc +q_004:abc +r_007:abc".  The requirement is to 
then configure fl to only include the stored fields psf_001, qsf_004 and 
rsf_007 in the response, but not the many other stored fields that are not 
relevant to the query.

What is the best way to accomplish this?  It would be convenient to be able to 
modify fl in the QParser.

Also, note that the index is not sharded. 

Thanks!

Jim

We are dealing with same thing, we have overridden QueryComponent (type of
SearchComponent) and added a field to retrieve there. That same field we are 
setting in SolrParams from query request. According to your business you need 
to figure out  how you can override QueryComponent. I hope this helps in 
solving your problem.

Re: Modifying fl in QParser

[Erik Hatcher]

And it's not necessary to override QueryComponent to set params.  I think I'd 
add a first-params SearchComponent, so you're decoupling and plugging in extra 
behavior rather than overriding kinda the heart of Solr.

We are dealing with same thing, we have overridden QueryComponent (type of

are setting in SolrParams from query request. According to your business

Re: Modifying fl in QParser

[Erik Hatcher]

Personally, I don’t think a QParser(Plugin) is the right place to modify other 
parameters, only to create a Query object.   A QParser could be invoked from an 
fq, not just a q, and will get invoked on multiple nodes in SolrCloud, for 
example - this is why I think it’s not a good idea to do anything but return a 
Query.

It is possible (in fact I’m dealing with this very situation with a client as 
we speak) to set parameters this way, but I don’t recommend it.   Create a 
SearchComponent to do this job instead.

Erik

RE: Modifying fl in QParser

[Alexandre Rafalovitch]

Your question is too dense. I, for one, have trouble parsing it, no pun
intended.

Could you expand it a little bit with business level problem, what you are
trying to achieve and what specifically is not working.

P.s. Also, many of us are in a different timezone from you and expecting a
response in a couple of hours for something like this might be a bit 
premature.

Hi,

Is it possible to modify the SolrParam, fl, to append selected dynamic fields, 
while rewriting a query in QParser.parse()?

Thanks in advance!
