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,

Partitioning the index

Hi,Is there a recommended index size (on disk, number of documents) for when to start partitioning it to ensure good response time? Thanks, S

display tokens

How can I retrieve the "analyzed tokens" (e.g. the stemmed values) of a specific field?

Lucene And SOLR

Is there a way to import a Lucene index (as is) into SOLR? Basically, I'm looking to enjoy the "web context" and caching provided by SOLR but keep the index under my control in Lucene.

Query Syntax (Standard handler) Question

queryResultCache

What is the best approach to tune queryResultCache ?For example the default size is: size="512" but since a document id is just an int (it is an int, right?) ,i.e 4 bytes why not set size to 10,000,000 for example (it's only ~38Mb). I sense there is something that I'm missing here :). any help wou

How do i normalize diff information (different type of documents) in the index ?

e.g. if the index is field1 and field2 and documents of type (A) always have information for field1 AND information for field2 while document of type (B) always have information for field1 but NEVER information for field2. The problem is that the formula will sum field1 and field2 hence skewing in

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 fiel

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

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,

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.
