c# - Nested range query in Lucene.NET -

i facing issue search ranges in lucene.net. have employee minrate , maxrate 2 fields in document. have search employees input again range minvalue , maxvalue. have filter employees, range overlaps in search range. if not then, should not return results.

my fields minrate, maxrate input fields or minval , maxval

i following approach, check minval in between minrate , maxrate - (+minrate:[0000 minval] +maxrate:[minval 1000])

then maxval between minrate , maxrate - (+minrate:[0000 maxval] +maxrate:[maxval 1000])

now have see if either 1 of query true results have displayed. have other filters also, when combined them, overall rate condition has mandatory.

any how approach helpful.
