That seems wise... PageRank * Text-based Scoring.
So you mean in my stupid case that:
GET '
http://127.0.0.1:8110/solr/test/select?indent=on&start=0&rows=100&q={!boostb=blogRank
v=$qq}&qq=*:*'
would yield the same results as:
GET
"http://127.0.0.1:8110/solr/test/select?indent=on&start=0&rows=100&q=*:*_val_:\"log(blogRank)\""
since I have no text data
but if I introduce a tokenized textfield (title).
Example:
<add>
<doc><field name="blogId">1</field><field name="title">solr solr
solr</field></doc>
<doc><field name="blogId">2</field><field name="title">solr/field></doc>
</add>
where blogId=1 had blogRank of 1
where blogId=2 had blogRank of 2
and if I searched for "solr"
GET '
http://127.0.0.1:8110/solr/test/select?indent=on&start=0&rows=100&q={!boostb=blogRank
v=$qq}&qq=title:solr'
I might get blogId=1 as nr1 in the results even though it had lower blogRank
due to the higher frequency of the term "solr" ?
Did I understand this correctly ?
