Subject: [OASIS Issue Tracker] Commented: (ODATA-139) New system query option $search for free-text search within an entity set
[ http://tools.oasis-open.org/issues/browse/ODATA-139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32005#action_32005 ]
Ralf Handl commented on ODATA-139:
----------------------------------
This is not an issue, instead it is a feature: the charming thing about a simple OpenSearch-like free-text search is that the only contract between client and server is "I give you a phrase, you give me results".
Search engines on the web prove how useful this contract is.
The server MAY look into related entities, or it may not.
It MAY look into all columns, or only those where a text search index exists.
Clients will use the search if the results are helpful.

> Key: ODATA-139
> URL: http://tools.oasis-open.org/issues/browse/ODATA-139
> Project: OASIS Open Data Protocol (OData) TC
> Issue Type: Improvement
> Components: OData ABNF Construction Rules v1.0, OData Protocol v1.0, OData URL Conventions v1.0
> Affects Versions: WD01
> Reporter: Ralf Handl
> Fix For: WD01

>
> Searching a list of entries by entering a free-text search phrase in a single input field is a very common UI pattern in mobile and browser-based applications.
> Translating this (typically case-insensitive) search phrase into an OData filter string is cumbersome and error-prone.
> A better alternative is providing a specialized query option that takes a search term and allows the server to interpret this search term.
> GET ~/Orders?$search=blue
> could return sales orders that somehow match the phrase "blue", without the client needing to specify where this phrase may occur. It even could appear in related entities, e.g. the description of one of the products ordered.
> This is comparable to Level 0 Conformance in CQL, see ODATA-3.
