hhm with a quick look I would suggest that you have to split the string
into individual terms, and then make a spannearquery for these Terms:
String[] que_ary = system_query.split("\\s");
//=> Array with third,party,licens,readme
SpanQuery[] spanq_ar = new SpanQuery[que_ary.length];
for (int i=0; i < que_ary.length; i++) {
spanq_ar[i] = new SpanTermQuery( new Term("TI", que_ary[i]) );
}
// now we have an array of spantermquerys
// each term of the sentence should be in exact order => spannearquery
// I am not sure if you'll better do a slop of "0"
SpanFirstQuery sfq = new SpanFirstQuery(
new
SpanNearQuery(spanq_ar,1,true), spanq_ar.length);
