Systems, methods, and computer-readable media for obtaining database records during an index update process are described. A database system may identify indexes having a first data format to be converted into a second data format, and obtain a first query for retrieval of a set of records in a database. The first query may comprise a filter to be used for retrieval of the set of records. The database system may convert the filter into the first data format to obtain a first filter value, convert the filter into the second data format to obtain a second filter value, and generate a second query to include the first data format filter and the second data format filter. The database system may issue the second query to obtain the set of records. Other embodiments may be described and/or claimed.
