When looking up old accounting documents such as payslips, invoices, tax statements, expense reports etc., date is one of the most important criteria. I’m looking for an index-based fulltext search program which would cover at least some of the following scenarios:
- search for a range of dates. If I search for “01.2001 to 12.2003”, it should find a document containing “01.04.2002”
- understand different date formats. If I search for “01.02.2003”, it should find documents containing “Feb 1 2003”, “2003-02-01” or “02/01/2003”
- language support. If I search for “February”, it should also find documents containing “février” and “febrero”
- support popular formats for accounting documents. Plain text and PDF is a must, popular office formats would be nice too
