See https://forum.image.sc/t/a-couple-of-queries-about-omero-web-iviewer-and-search-by-key-value-pairs/47334/8

A couple of features requested that are available in webclient:

• For Key-Value filtering, would like to have auto-complete of the Values for a chosen key
• For numerical Key-Value pairs, provide filtering by > < = etc.
