Vijay Sekhri commented on SOLR-5743:
------------------------------------
I saw the blog few times before already. Thank you for writing it Mikhail . I
am not sure it cover the searching uses cases. Searching and filtering are two
different use cases.
For example say you have these in your solrconfig as one of the requesthandler
. As you can see it would search in a lot fields and boost based on which
fields matches. Plus if you declare pf field for proximity and mm field for
must match , relevancy kicks in . All of this I am not sure how can be still
used just by mere filter. Searching return relevant docs with accounting for
boosts. Filter remove docs that matches criteria.
<code>
<str name="qf">
primaryLnames^5.0 partnumber^11.0 itemnumber^11.0
description^0.5 fullmfpartno^5.0 mfpartno^5.0 xref^10.0
storeOriginSearchable^3.0 nameSearchable^10.0 brandSearchable^5.0
searchPhrase^1.0 searchableAttributesSearchable^1.0
</str>
<str name="pf">
primaryLnames^0.5 nameSearchable^1.0
description^0.1 storeOriginSearchable^0.3 brandSearchable^0.5 xref^1.1
searchableAttributesSearchable^0.1
</str>
<str name="fl">*</str>
<str name="mm">
2<-1 5<-2 6<-50%
</str>
</code>
Let me know if there is a way to still search, not filter and still use
ToParentBlockJoinQuery . Real world scenarios would return parent docs based on
some order of relevancy and boost criteria.

> For a sample inventory(note - nested documents) like this -
> <doc>
> <field name="id">10</field>
> <field name="type_s">parent</field>
> <field name="BRAND_s">Nike</field>
> <doc>
> <field name="id">11</field>
> <field name="COLOR_s">Red</field>
> <field name="SIZE_s">XL</field>
> </doc>
> <doc>
> <field name="id">12</field>
> <field name="COLOR_s">Blue</field>
> <field name="SIZE_s">XL</field>
> </doc>
> </doc>
> Faceting results must contain -
> Red(1)
> XL(1)
> Blue(1)
> for a "q=*" query.
