This syntax is a WiP and could change at any time. Currently, it allows for:

• Simple singular WORD (e.g., haxby) or a "QUOTED STRING" (e.g., "James V. Haxby")
  • Searching is case-insensitive at the moment, so haxby is identical to Haxby.
  • Searching is performed within content rather than for entire words, and so searching for ax would find Haxby, tax, etc.
• By default, the following fields are searched: "url", "ds_id", "head", "head_describe", "branches", "tags", "metadata". To restrict the search to a specific field, specify the field name followed by : and the search term, e.g., url:github or head:1.0 or metadata:"James Haxby".
• AND, OR, and NOT can be used for logical operations.
  • The default logical operator is AND, and so searching for James Haxby is identical to searching for James AND Haxby or Haxby AND James.
  • AND and OR may not be mixed in the same statement.
• Use ( and ) to group statements, e.g., (url:github.com OR url:gin.g-node) AND (Haxby (James OR Jim)).
• You can restrict a search to specific metadata extractors by specifying one or more of them, e.g., metadata[bids_dataset,metalad_core]:"BIDSVersion\": \"v" where the backslash is an escape character, and the letter v is a stand-in for an actual version string.
