I am trying to play a little bit with RavenDB 4.0 RC. I am migrating from RavenDb 3.0 to the latest version.
The problem I have is extension method IRavenQueryable<T> IQueryable<T>.Where<T>(System.Linq.Expressions.Expression<Func<T, bool>> predicate, bool exact)
What parameter exact actually do? From my investigation when I set that to true RavenDB is not giving me results from the queries along with Index, where part of the query is string comparison.
I couldn't find any documentation of RavenDB 4.0 just yet, so maybe anyone came across that and could give me some explanation of what that parameter is?
The book about RavenDB 4.0 is currently being written, but can be download right now here: https://github.com/ravendb/book/releases/tag/v4.0.9-preview
In particular, this controls whatever the query will use exact(State = 'abc').
The exact behavior controls how RavenDB will treat the query by default. In this case, unlike the use case insensitive behavior, this will generate a case sensitive match.
This is applicable only for queries that don't use an index, in which case the definition specified on the index fields take precedence.
