Documentation on boost functionstrings

[Robert]

Hey guys,

Can you shed some light on what functionstrings are in the search API.

See: http://www.thriftdb.com/documentation/rest-api/search-api
-> boosts[functions][<functionstring>] = float

Does the functionstring represent a formula for score calculation?

Function strings are functions that conform to the solr function query syntax:

You can use function boosts to rank matches by functions such as an exponentially decreasing function of time:

&boosts[functions][pow(2,div(div(ms(create_ts,NOW),3600000),72))]=10.0
