XQuery/Basic Search

Motivation You want to create a basic HTML search page and search service. Method We will create two files. One is an HTML form and the other is a RESTful search service that takes a single parameter from the URL which is the search query. The search service will search a collection of XML files. Here is the base path to our test search collection: /db/test/search The data to be searched will be in the following collection: /db/test/search/data In "Browse Collections" in the Admin interface, create the collection "test"; create the collection "search" under it; lastly, create the collection "data" under "search". Upload the two XML documents listed under "Sample Data" to "data"; upload "search-form.xq" and "search.xq" to "search" (instead of uploading, you can Save to URL, using oXygen, or use the Webstart client). Search Form /db/test/search/search-form.xq We will create a basic HTML form that has just one input field for the query. declare option exist:serialize "method=xhtml media-type=text/html indent=yes"; let $title := 'Basic Search Form' return <html> <head> <title>{$title}</title> </head> <body> <h1>{$title}</h1> <form method="GET" action="search.xq"> <p> <strong>Keyword Search:</strong> <input name="q" type="text"/> </p> <p> <input type="submit" value="Search"/> </p> </form> </body> </html> Note that the action will pass the value from the form to a RESTful service. The only parameter will be "q", the query string. Search Service The following file should be placed in /db/test/search/search.xq /db/caldeirao/search/search.xq xquery version "1.0"; declare option exist:serialize "method=xhtml media-type=text/html indent=yes"; let $title := 'Simple Search RESTful Service' let $data-collection := '/db/test/search/data' (: get the search query string from the URL parameter :) let $q := request:get-parameter('q', '') return <html> <head> <title>{$title}</title> </head> <body> <h1>Search Results</h1> <p><b>Searching for: </b>{$q} in collection: {$data-collection}</p> <ol>{ for $fruit in collection($data-collection)/item[fruit/text() = $q] return <li>{data($fruit)}</li> }</ol> </body> </html> Running your Search To test your search service from a URL, copy the following into the browser navigation toolbar: http://localhost:8080/exist/rest/db/test/search/search.xq?q=apple You should see the following result: center|frame To drive this service from a form, click the following link or copy it into your browser navigation toolbar: http://localhost:8080/exist/rest/db/test/search/search-form.xq center|frame Sample Data for /db/test/search/data /db/test/search/data/1.xml <item> <fruit>apple</fruit> </item> /db/test/search/data/2.xml <item> <fruit>banana</fruit> </item>
