Enhance search bar for comparison table

[Kr0nox]

The search bar could be enhanced and made more powerful

• [ ] search by number for index (maybe also with an optional prefix like index:#number) to display single comparisons in the table
• [ ] filter for similarities (e.g. >80 only displays comparisons with more than 80% in any similarity, avg:>80 only displays comparisons with more than 80% average similarity)
