Leave behind all spreadsheets. There is no technical reason nor convenience factor in favour of using spreadsheets with a database dump of raw data. The dBase driver of the Base component supports indexing for fast lookups within millions of rows. Save as dBase in a *dedicated directory*. dBase is a database in a directory.
Connect a Base document to the *directory*.
Open the table for editing and add some indices on relevant fields.
Create a set of simple queries. Parameter queries are supported.
