Question

I consider this solr psedo-doc

<doc>
<field name="title"/>
<field name="name"/>
<field name="keywords"/>
</doc>

Some doc’s will have the keyword “up” which means that they should appear first (despite of their initial order position) when and only when they are part of the search results.

So lets say I have:

doc1('title1','Bob, Alice','people, up, couple')
doc2('title2','Smart Phone, Laptop, Bob','devices, electronics')

if I query with “title:title2 name:Bob” then I should get doc1 first (it has the ‘up’ keyword).
if I query with “name:Bob” I still get doc1 first for the same reason.
if I query with “name:Laptop” then I should only get doc2 in my results. doc1 should not be included since it doesnt match my search query.

Any suggestion to do this?

You have several options to do something like that:

• function query / boost query (in dismax handler)
• during index time (boost documents)
• extract ‘up’ keyword to additional field and sort by this field, than score

For example (with dismax handler):

 /select?defType=dismax&q=...&bq=keywords:"up"^1000
