Re: How to change the weight of the fields ?

Vincent,

You need to add defType=dismax when using bf parameter.

Please see:

Hello,

I'm stuck my the boost feature...

I'm doing the following query :

http://localhost:8983/solr/select/?q=novel&bf=title_s^5.0&fl=title_s+isbn_s&version=2.2&start=0&rows=5&indent=on&debugQuery=on

Below a part of my debug (the results are correct) :

<lst name="debug">
<str name="rawquerystring">novel</str>
<str name="querystring">novel</str>
<str name="parsedquery">text:novel</str>
<str name="parsedquery_toString">text:novel</str>
−
<lst name="explain">
−
<str name="Listing:397">

0.6041825 = (MATCH) fieldWeight(text:novel in 395), product of:
  1.7320508 = tf(termFreq(text:novel)=3)
  3.1892564 = idf(docFreq=55, numDocs=500)
  0.109375 = fieldNorm(field=text, doc=395)
</str>

<str name="Listing:445">

0.51787066 = (MATCH) fieldWeight(text:novel in 443), product of:
  1.7320508 = tf(termFreq(text:novel)=3)
  3.1892564 = idf(docFreq=55, numDocs=500)
  0.09375 = fieldNorm(field=text, doc=443)
</str>


It seems Solr is only evaluating the 'text' field and skip the 'title_s'
field.
The line in the schema for dynamic string is :

<dynamicField name="*_s" type="string" indexed="true" stored="true" omitNorms="false" />

Do I need to enable something else to be able to change the weight of my
fields?

Thanks very much
Vincent
