| Parameter | Description |
|---|
| author | Entry author. Service returns entries where the author name or email matches the query string. |
| itemsPerPage | Number of result items to retrieve per page. |
| orderBy | Expression for sorting a collection of results. The format is ?orderBy=<field name> <sort order>[, <field name> <sort order>]. Ascending / descending order is specified by appending “asc” or “desc”. Examples: - http://api.example.org/resource?orderBy=updatedAt desc,material-format asc
|
| publishedMin, publishedMax | Bounds on entry publication date. |
| q | Full-text query string.
Keyword search- A keyword search uses one or more complete words that are contained anywhere in the item's record.
- Example: q=dog
Phrase search- A phrase search uses quotation marks to allow an exact match to the phrase searched.
- Example: q=”exact phrase search”
Boolean operators- Boolean operators allow you to group, include, or exclude certain terms in your search.
- AND operator. When creating a query, list search terms separated by spaces, in the form q=term1 term2 term3. As with all of the query parameter values, the spaces must be URL-encoded. The service returns all entries that match all of the search terms (like using AND between terms).
- Example: q=book hardcover collector
- OR operator. The use of OR will search for either of the terms listed in the query string, q=term1 OR term2.
- Example: q=dog OR cat
- Exclude operator. The minus sign (-) will exclude terms from your search. Specify the query as q=term1 – term2.
- Example: q=paris – fashion (meaning search for paris but not fashion)
- Parenthesis can be used to further specify order of operations within the boolean query. The order of operations should be handled as follows: a) inner most parens, b) exclude operator, c) AND operator, d) OR operator.
- <Example: q=dog AND ((cat OR food) - treats)
Wildcards- Wildcards are special characters used to represent additional characters in a search term. They are useful when you are unsure of spelling, when there are alternate spellings, or when you only know part of a term.
- Pound sign (#). The pound sign, also called a number sign or hash mark, represents a single character.
- Example: q=wom#n Returns items whose record contains “woman”, “women”, etc.
- Question mark (?). The question mark (?) represents any number of additional characters.
- Example: q=m?n Returns items whose record contains “man”, “men”, “moon”, “maroon”, etc.
Truncation- Truncation allows you to search for a term and its variations by entering a minimum of the first three letters of the term followed by an asterisk (*).
- Example: q=invest* Returns items whose records contain “investor”, “invested”, “investing”, “investment”, etc.
General- The search is case-insensitive.
- To allow for index specific searching, specify the query as index:term. Example: q=title:dog and title:cat
- The absence of the “q” parameter will default to return all items available for that service. It is the same as specifying q=* to return all items in the service.
|
| startIndex | 1-based index of the first result to be retrieved |
| strict | Strict query parameter checking.- Set strict=true to have the service verify that each of the query parameters are recognized by the service.
- Default strict=false
|
| updatedMin, updatedMax | Filter by entry update date. |
Custom Query Options
A custom query option is any query string parameter not defined as part of this standard set query parameters. Web services may support custom query parameters for web-service-specific functionality.
