genericsearch's Issues

Complex conditions

Do you think it would be possible to modify the logic to allow complex conditions? By complex I mean something like (stupid example):

WHERE (Email like '%test%' AND BrithDate < 01/01/1980)
   OR (Email like '%anothertest%' AND BirthDate > 01/01/1980)

Support for complex collections

Currently only simple collections are supported: n => n.SimpleCollection

Complex nested collections should be supported as well: n => n.Collection.Select(c => c.PropertyName)

Filter on nulls

There is no way at the moment to filter on null values. For example I would like to filter for null IntegerNullable values.

Thanks...

...for this very nice piece of work :)

method ApplySearchCriterias forces excess request to DB

.ToArray() forces query evaluation, but result variable isn't used
