Any entity can be annotated with metadata, which can be used for searching. In Datagrok, there are three kinds of metadata: tags, parameters, and properties.
A tag is a short string that can be associated with any entity. It is convenient for grouping things (potentially of different kings) together.
To search for tagged entities, enter '#tagname' in the search box.
Each entity can be associated with a list of key-value pairs.
To search for entities with the specified parameters, use the
<paramName> <op> <value> syntax, for instance:
imported < 10/02/2019
rows > 200
author = @current
Properties are somewhat similar to parameters, however they might contain nested properties; also, they are not directly editable. Some properties are common for all entities, others are specific to the entity type.
Search criteria can be combined using 'and' or 'or' operands:
#demo or #chem
