The "FunctionQuery" page has been changed by YonikSeeley. http://wiki.apache.org/solr/FunctionQuery?action=diff&rev1=26&rev2=27 -------------------------------------------------- = Using FunctionQuery = There are a few ways to use FunctionQuery from Solr's HTTP interface: 1. Embed a FunctionQuery in a regular query expressed in SolrQuerySyntax via the _val_ hook - 1. Use the FunctionQ!ParserPlugin, ie: {{{q={!func}log(foo)}}} + 1. Use the FunctionQParserPlugin, ie: {{{q={!func}log(foo)}}} 1. Use a parameter that has an explicit type of FunctionQuery, such as DisMaxRequestHandler's '''bf''' (boost function) parameter. * NOTE: the '''bf''' parameter actually takes a list of function queries separated by whitespace and each with an optional boost. Make sure to eliminate any internal whitespace in single function queries when using '''bf'''. * Example: {{{q=foo&bf="ord(popularity)^0.5 recip(rord(price),1,1000,1000)^0.3"}}} - See http://wiki.apache.org/solr/SolrPlugins#head-566d72e9c5e48b8c9fd8ae5c898d9e06917a7bb3 for information on how to hook in your own FunctionQuery. + See SolrPlugins#ValueSourceParser for information on how to hook in your own FunctionQuery. Note that a FunctionQuery matches all non-deleted documents.
