Re: How to change the boost of fields in edismx at runtime

[roz dev]

Thanks Hoss.

Yes, that approach would work as I can change the query.

Is there a way to extend the Edismax Handler to read a config file at
startup and then use some events like commit to instruct edismax handler to
re-read the config file.

That way, I can ensure that my boost params are just on on Solr Servers'
config files and If I need to change, I would just change the file and wait
for commit to re-read the file.

Any inputs?

 edismax field boosts (specified in the qf and pf params) can always be
 specified at runtime -- first and foremost they are query params.

 when you put then in your solrconfig.xml file those are just as defaults
 (or invariants, or appends) of those query params.

Hi Saroj,

You could use the boost function in a FunctionQuery. Something similar to,

_val_:Title^10 and _val_:Keyword^2
_val_:Title^2 and _val_:Keyword^10

See
http://wiki.apache.org/solr/SolrRelevancyFAQ#How_can_I_boost_the_score_of_newer_documentson
how to use the boost function.

Thanks,
Indika

 Hi All

 I am wondering if there is any way in which we can change the relative
 boost of different fields in edismax, at the run-time.

 For example, I can define 2 fields in my edismax query

 -Title - boosted to 10
 -Keyword - Boosted to 2


 Then, If I find that results are not of my liking then I would like to
 change the boost as following

 - Title - boosted to 2
 -Keyword - boosted to 10

 Is there any way to change this boost, at run-time, without having to
 restart solr with new boosts in edismax?

 Any thoughts are much appreciated.

 Thanks
 Saroj
