Indexing lists of IDs
Hello,
I have document for which I'd like to index an array of indexes. For
example, there is a product that belongs to categories with IDs 12, 15, 16,
145, 148. I'd like to index these categories, and then be able to use them
in queries, so that I can search for product which's name is "Bottle" and
which belongs to category 12.
I came up with creating a field in which I store the ID numbers and separate
them with spaces. However, when I tried to create a term query, the query
never gave any results. Can anybody help me with this?
Sincerely,
Kristjan Siimson

Thanks, the problem was with tokenizer, which didn't index any numbers, so I
tried writing my own, and it works perfectly! :)

You can add the terms with Field.Index.NOT_ANALYZED multiple times to the same field. If you use an analyzer like WhitespaceAnalyzer and you analyze your tersm, you must also pass the analyzed term through analyzer when building a TermQuery. This may explain, why you don’t get those IDs.
But for IDs in general, you should not use analyzers and add as NOT_ANYLYZED and query with TermQuery. As explained before, just add more than one term to the same field.

Hi Kristjan,
which Tokenizer and Filters are you using for the ID field?
