Hi ,
discussed here [0], it will soon become necessary to add support for indexes on attribute table manipulation during selection operations.

Search and advanced search have poor performances on large tables because datasource indexes are not used.

Ideally, when implemented, Internal indexes for fields should be built on load where original datasources have indexes .

We should also care that user clearly understand the difference between building indexes in the cache vs. datasource. maybe, we should add the capacity to write indexes for providers that support that feature.
