Enable searching/filtering on entities based on interval properties (one-hop)

[brrttwrks]

The OCCRP Data Desk receives many requests to enable filtering of entities based on the properties of their intervals using the UI. For example in a search or xref.

Ex. 1. I am looking at a datasets legal entities entity types that have made payments and want to filter those legal entities by those who have made payments greater than 5,000,000. I would like to export those payments as a spreadsheet.

Ex. 2. Not sure if this is best place for XREF, but similarly XREF should be searchable/filterable just as search results are. Journalists are often confused by filters are more limited in XREF. At the very least, and maybe low-hanging fruit - be able to filter the XREF by name/title - journalists often want to find matches across other datasets of just one person and XREF always returns all the matches and a journalist has to scroll down to see if a particular name has a match.
