java - Regexp Query in Lucene -

i working lucene search, having list of names like

1) city of cairo 2) calicut official branch 3) cairo branch office

if user types "co", have bring names start "c" , sec word should start "o", should homecoming 1st name(city of cairo) , 2nd name (calicut official branch). 3rd name(cairo branch office) name should not returned, not having second word started "o". using regexpquery query. listing above 3 names wrong.

regexpquery dynamicregex3 = new regexpquery(new term("name", "c.* o.*"));

what way accomplish ?

printed query :::: name:/c.* o.*/

your regex greedy, utilize instead:

regexpquery dynamicregex3 = new regexpquery(new term("name", "c[^ ]* o.*"));

[^ ] stands character not space.
