I can't find how to do so, to be able to search on certain fields of the table.
For example, there is a table of the form:
It is specified as a source for indexing.
If you to query the created index, the search will be performed on all fields at once. But the user has the possibility to specify what fields you want to search, for example, only on Field2 and Field3.
Is it possible to make it so that we can search for matches on different fields without generating all possible codes from the combinations of different fields?
