Embed a FunctionQuery in a regular query expressed in SolrQuerySyntax via the _val_ hook + 1. Use the FunctionQ!ParserPlugin, ie: {{{q={!func}log(foo)}}} - 2. Use a parameter that has an explicit type of FunctionQuery, such as DisMaxRequestHandler's '''bf''' (boost function) parameter. + 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=dismax&bf="ord(popularity)^0.5 recip(rord(price),1,1000,1000)^0.3"}}}
