Member Function Documentation

static Query WorldNet.Net.SynExpand.Expand ( String  query, Searcher  syns, Analyzer  a, String  field, float  boost  )

static

Perform synonym expansion on a query.

Parameters

query	users query that is assumed to not have any "special" query syntax, thus it should be just normal words, so "big dog" makes sense, but a query like "title:foo^1.2" doesn't as this should presumably be passed directly to the default query parser
syns	a opened to the Lucene index you previously created with Syns2Index. The searcher is not closed or otherwise altered.
a	optional analyzer used to parse the users query else StandardAnalyzer is used
field	optional field name to search in or null if you want the default of "contents"
boost	optional boost applied to synonyms else no boost is applied

Returns

the expanded Query

static void WorldNet.Net.SynExpand.Main ( String[]  args )

static

Test driver for synonym expansion. Uses boost factor of 0.9 for illustrative purposes.

If you pass in the query "big dog" then it prints out:

Query: big adult^0.9 bad^0.9 bighearted^0.9 boastful^0.9 boastfully^0.9 bounteous^0.9 bountiful^0.9 braggy^0.9 crowing^0.9 freehanded^0.9 giving^0.9 grown^0.9 grownup^0.9 handsome^0.9 large^0.9 liberal^0.9 magnanimous^0.9 momentous^0.9 openhanded^0.9 prominent^0.9 swelled^0.9 vainglorious^0.9 vauntingly^0.9
