You need to use Lucene.Net.Search.NumericRangeQuery, this query matches numeric values within specific range.

In your case (in Lucene syntax) it would be:

max:[value TO *] AND min:[* TO value]

Where value is your input. If you want to the values to be exclusive - you should use { instead of [

In Lucene.NET it should be something like this:

Query q = NumericRangeQuery.newFloatRange(“fieldName”, new Float(value), float.MaxValue, true, true);

And similar for second part, with replacing * to a minimum float value
