Usage Guide

Basic Syntax

Expressions you type in the text field are broken down into "terms". A term is either a single word, or an item in between quotation marks (""). For a basic search, you can type a single term into the box (e.g. "dorsal fin" or puppies). For a more complex expression, you use groups of three terms (ingeniously called triples), which are broken down into the annotation type, the operator, and the search term. For example, if you want all entities that have comment annotations that contain the term "dermal bone", you would search: comment contains "dermal bone". If you want to search for an even more complex expression (for example, you know the comment annotation contains the phrase "phenoscape" and the age annotation is greater than 19), you break the two search terms up with a logical operator (and, or, exclusiveor). So in this example, your search string would be: comment contains phenoscape and age > 19.
