Search Query Syntax

Hi! Today I'll walk you through Lucene search engine syntax to make the best use of clojars website.

We can see a search query as a bunch of terms and operators, let's explore several ways to use our search engine:

Terms

There are 2 types of terms:

• A term is a single word such as oauth or sql
• A phrase is just a bunch of words grouped by quotes, like "sql builder"

Boolean operators

Terms can be combined with operators in order to build less simple queries:

• AND matches both terms, i.e. google AND oauth
• NOT excludes the term after NOT, i.e. auth NOT SNAPSHOT
• OR matches if either of the terms is present, i.e. ldap OR saml

Grouping

Parentheses can be used to form sub queries, i.e. (ldap OR saml) AND ADFS

Wildcards

• ? single character wildcard search for terms that matches with a single character replaced, i.e. oauth?
• * multiple character wildcard searches for 0 or more characters, i.e. oauth*

Do not use ? or * as the first character of a search
