Search numbers and dates

The simplest solution is to store 2 fields with the same data in 2 different formats. An index is not a database, there is no rule that says that duplicating the data is bad. You just have to keep in mind that BoboBrowse.Net has these requirements and design the index to work with these formatted string data types as well as any other types you require. If you need to make them native data types for some other reason, you just need to add another field to the document.

int number = 19;

string numberFormatted = number.ToString("000000", System.Globalization.CultureInfo.InvariantCulture);
Field f = new Field("numberBobo", numberFormatted, Field.Store.NO, Field.Index.NOT_ANALYZED_NO_NORMS);
f.OmitTermFreqAndPositions = true;
doc.Add(f); 

Field f2 = new NumericField("number").SetIntValue(number);
doc.Add(f2);

In the above case, you would use the "numberBobo" field with one (or more than one) facet handlers. But the index is still tracking the numeric field "number" in case you need to utilize it in another way, such as for search and/or feeding it back to the application after a hit is made.
