Reading a prameter set in browser in request handler

[Mark Robinson]

Hi,

I pass a parameter *&country=USA* from the browser as part of my query.
(I have fields *weather_USA*, *weather_UK* etc... in my document).
How do I retrieve the parameter "country" in my requesthandler.

I tried in my requesthandler:-


storeId
weather_${country}

...but it is not working.  Even tried:-
 weather_$country

I am trying to set my weather field based on the *country *passed.

  Any suggestionsis is highly appreciated.

Thanks!
Mark

The variable substitution in the solrconfig.xml happens when that file
is loaded, right at the start of core initialization. Your request
variable comes much later. I don't think you can expand it this way.

Could you explain a bit more what you are trying to achieve in
business terms. E.g. 'weather' term needs to feed into something else
in query I am guessing.

Alex.

Thanks Alex for the reply.

Yes. in this context I want to determine the weather of the country passed
from browser which will go into another function query.

If I do the above directly from the browser it works great. I am trying to
move this to the requesthandler so that I need to pass only the country
name which is what varies.
If all parameters in the browser itself:-
&country=USA&climate=if (weatherDetermine, weather_${country},
defaultField).

Basically  I am trying to configure most of my params in request handler so
that I need to pass only one param that actually varies, reducing my query
url length.

So baseically was trying to find out *how I can access a parameter passed
from the browser in a request handler to determine on a field dynamically
using the info passed from browser.*

Thanks!
Mark

Re: Reading a prameter set in browser in request handler

You've got Parameter Substitution:
https://cwiki.apache.org/confluence/display/solr/Parameter+Substitution

I think this should do the trick. Perhaps combined with switch query
parser as 
https://cwiki.apache.org/confluence/display/solr/Other+Parsers#OtherParsers-SwitchQueryParser
(like in an example here:
https://gist.github.com/arafalov/5e04884e5aefaf46678c )

Re: Reading a prameter set in browser in request handler

[Walter Underwood]

We have a different problem, then.

Accessing Solr directly from the web is a very, very bad idea. Solr is not 
designed for hostile web access. I’m glad to share with you a simple command 
that will delete all the documents in your index. Works great.

So step #1 is to put some kind of server between the browser and Solr. That 
server can make substitutions. Or you can have a request handler for each 
locale.

Re: Solr Wide Column - not work when with 200k dynamic fields

Hi, Alexandre Rafalovitch
Sorry for the late reply. Trying to find time to use nested documents and
implement the code .
Thanks so much for your reply and suggestion. It totally make sense.
