Lucene index field not searchable

Question

So I have a field in my Lucene index documents named "Field1" (for all intents and purposes).

When I open Luke, and browse the documents, I see most of the documents have this field. However when I switch to the search tab, and I input Field1:parameterValue I get zero search results.

When doing the indexing, for the document, I have

doc.Add(new Field("Field1", field1, Field.Store.YES, Field.Index.ANALYZED));

Why is my field not able to be searched? As an aside, I can't find any documentation on Luke that explains what the "IdfpTSVopNLB#" column is in the document record either. I'm thinking this information could possibly be useful, so for one of the records that has this field, the column value is IdfpTS---N--- and the "Norm" column is 4.0

Answer 1

The "IdfpTSVopNLB#" field is a collection of flags. You should see a key to it in Luke:

I would guess the reason your searches are failing is because you aren't taking your analysis into account. For instance, for your sample query: Field1:parameterValue, if the field is analyzed by StandardAnalyzer (and the query is not analyzer or is keyword analyzed), you'll get no results. This is because "parameterValue" would have been lowercased by the analyzer, so the actual searchable term would be "parametervalue", instead.

In the search tab, you should see a place to select an analyzer for Luke to use for query parsing. If you use the same analyzer you used to index the data, you may see better results.

Answer 2

As it turns out, this is the correct way to do this. I just needed to delete the entire index and rebuild it from scratch to get the new values in. It didn't automatically update the existing indexes.
