search #

Searches documents.

There is a limit to how many documents can be returned by a single search query. That limit is by default set at 10000 documents, and you can't get over it even with the from and size pagination options.

When processing a large number of documents (i.e. more than 1000), it is advised to paginate the results using SearchResult.next rather than increasing the size parameter.
