Solr: edismax boost not working
I'm playing with following query but can't get the *object_desc* field
boosted correctly. Maybe someone can tell me what I'm missing here:
&wt=json&&defType=edismax&indent=on
&q=object_name_NGRAM:video OR object_desc_NGRAM:video
&qf=object_desc_NGRAM^10 object_name^2
field definition:
<fieldType name="text_ngram" class="solr.TextField"
positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.StandardTokenizerFactory"/>
<tokenizer class="solr.LowerCaseTokenizerFactory"/>
<filter class="solr.EdgeNGramFilterFactory" minGramSize="1"
maxGramSize="50"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.StandardTokenizerFactory"/>
<tokenizer class="solr.LowerCaseTokenizerFactory"/>
</analyzer>
</fieldType>
<field indexed="true" multiValued="true"
name="object_name_NGRAM"
required="false"
stored="false"
type="text_ngram"/>
<field indexed="true" multiValued="true"
name="object_desc_NGRAM"
required="false"
stored="false"
type="text_ngram"/>
example documents:
<doc>
<field name="id">1</field>
<field name="object_name_NGRAM">video gaming</field>
<field name="object_desc_NGRAM">economic</field>
</doc>
<doc>
<field name="id">2</field>
<field name="object_name_NGRAM">economic</field>
<field name="object_desc_NGRAM">video</field>
</doc>
<doc>
<field name="id">2</field>
<field name="object_name_NGRAM">video gaming is an economic
business</field>
<field name="object_desc_NGRAM">gaming</field>
</doc>
I want to boost to show the document having id=2. but my query is no
working.

bq: I want to boost to show the document having id=2. but my query is
no working.
Exactly _how_ is it not working? Boosting just influences position, it
doesn't impose an absolute order. It's quite possible that you're
successfully changing the score, just not enough to show.
Use the debug=all, perhaps with explainOther just to see. The faster
test would be to return the score with the document and try several
different boosts to see if the score changes.
Best,
Erick

Hi Ruby,
Just add fields you want to search in qf and set boost for it. And yes - it can be defined in search handler params - you can set defaults or even use invariants to ignore values passed in url.
Edismax has quite a few parameters and you should check docs to see how to use them in your scenario.
HTH,
Emir

Thanks that worked. But now if I want to search against 3 fields, can that be
defined in solrconfig.xml?

Hi,
Can you try:
&wt=json&&defType=edismax&indent=on
&q=video
&qf=object_desc_NGRAM^10 object_name^2
It is edismax that expands query to search in fields listed in qf.
HTH,
Emir
