Keyword Searching in the Browser

Published: 24 November 2014
The Browser image searching tool has a powerful keyword search box.

It is fundamentally, the same as the keyword search on the main search, and supports most of the same syntax.

This article attempts to document the difference.

Note, the 'Browser index' is also used by the simplified 'Photos of' interface, the Groups By tester, and the coverage layer. (and a few other experimental tools)

Missing features

~ operator does not work in the browser
[...] tag syntax is only partly supported, not recommended to use.
Field Start/End modifiers, don't work on Tags/Context etc

Field Searches

The browser index has its own list of available search fields.

Can use 'field syntax' to limit keywords to a specific field. If specify field name followed by colon, ALL keys after that (or until another specifier!), will only match specific field.

eg [ bridge title: canal liverpool] will look for 'bridge' in ANY field. But 'canal' and 'liverpool' needs to be in the image title.

This is a full reference list: (some are intended for internal use, so not easy to use)
