Weighting the Licene score

I want to weighted average the Lucene score with an additional score i have, i.e. (W1 * Lucene score + W2 * Other score) / (W1 + W2) . What is the easiest way to do this? Also, is the Lucene score normalized. Thanks,

Interleaved results form different sources

We have an index of documents from different sources and we want to make sure the results we display are interleaved from the different sources and not only ranked based on relevancy.Is there a way to do this ? Thanks, S.

Inconsistent results

Hi,I use SOLR with standard handler and when i send the same exact query to solr i get different results every time (i.e. refresh the page with the query and get different results). Any ideas? Thx,

Performance - FunctionQuery

Adding a FunctionQuery made the query response time slower by ~300ms, adding a 2ndFunctionQuery added another ~300ms so overall i got over 0.5sec for a response time (slow).Is this expected or am i doing something wrong ? Thx

Min-Score Filter

Is there a way or a point in filtering all results bellow a certain score? e.g. exclude all results bellow score Y.Thanks

DisMax Syntax

User Query: x1 x2 Desired query (Lucene): field:x1 x2 field:x1 x2~a^b In the standard handler the only way i saw how to make this work was: field:x1 field:x2 field:x1 x2!a^b Now that i want to try the DisMax is there a way to implement this without having duplicate fields? i.e. since the fields

Re: DisMax Syntax

I may be mistaken, but this is not equivalent to my query.In my query i have matches for x1, matches for x2 without slope and/or boosting and then match to x1 x2 (exact match) with slope (~) a and boost (b) in order to have results with exact match score better. The total score is the sum of all

Is there a way to retrieve the analyzed tokens (e.g. the stemmed values) of a field from the SOLR index ? Almost like using SOLR as a utility for generating the tokens. Thanks !
