[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-960) Index.UN_TOKENIZED overrides other tokenized fields that share the same name

Sanne Grinovero commented on HSEARCH-960:
-----------------------------------------

Right. Your explanation makes it sound a limitation of how we do it, but it's just a Lucene API limitation; sorry for not thinking about that right away.

I'd vote for the warning to be logged for now.

In the long term, we could actually work around Lucene's limitation implementing pre-index tokenization; something which is on my whish list to improve clustering.

> Marking one field as un-tokenized causes all other fields with the same names to be un-tokenized.
> i.e.
> {code}
> @Field(name = "simple_search", index = Index.UN_TOKENIZED, store = Store.NO)
> private String string;
> @Field(name = "simple_search", index = Index.TOKENIZED, store = Store.NO)
> private String string2;
> {code}
> The resulting behaviour is that "simple_search" will be made up of un-tokenized 'string' and 'string2' values, even though 'string2' was specified to be tokenized.
