[opencms-dev] Search in field of structured content

[Steve Bryan]

Some more detail on how to search in structured field:

Config can be done via the OpenCms workplace in Administration view, or
direct in opencms-search.xml

 

You need to 

1. Create a search index and an associated index source. The source defines
the area of your website that is indexed, and the index maps on to a folder
where the Lucene search indexes are stored. 

http://www.applecentreorchard.com/moby/cms/alkacon-documentation/documentati
on_search/search_howto.html

 

Your source will need to include XML type ('xmlcontent').

 

eg - in my site I allow search over a Holiday XML type, that is contained in
a folder with path /sites/dtw/metadata/holiday/.

 

            <index>

                <name>Holiday</name>

                <rebuild>auto</rebuild>

                <project>Online</project>

                <locale>en</locale>

                <configuration>holiday</configuration>

                <sources>

                    <source>Holidays</source>

                </sources>

            </index>

            <indexsource>

                <name>Holidays</name>

                <indexer class="org.opencms.search.CmsVfsIndexer"/>

                <resources>

                    <resource>/sites/dtw/metadata/holiday/</resource>

                </resources>

                <documenttypes-indexed>

                    <name>xmlcontent</name>

                </documenttypes-indexed>

            </indexsource>

 

 

2. Notice the element <configuration>holiday</configuration> in the <index>
tag. This tells the index to use field mappings.

 

            <fieldconfiguration>

                <name>holiday</name>

                <fields> 

                    <field name="Title" store="true" index="false">

                        <mapping type="item">Title[1]</mapping>

                    </field>

                    <field name="SortTitle" store="true"
index="untokenized">

                        <mapping type="item">Title[1]</mapping>

                    </field>

                    <field name="Price" store="true" index="true">

                        <mapping type="item">Price[1]</mapping>

                    </field>

                    <field name="Duration" store="true" index="true">

                        <mapping type="item">Duration[1]</mapping>

                    </field>

                    <field name="Image" store="true" index="false">

                        <mapping type="property">image</mapping>

                    </field>

                </fields>

            </fieldconfiguration>

 

This store="true" means I can read the field in the results, and
index="true" means it is available to search on. I sort the results on
"SortTitle".

mapping type="item" maps elements to lucene fields.

mapping type="property" maps properties of the xml files (I have an image
property set on the xml objects externally).

 

 

Here's my holiday schema:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">

          

          <xsd:include schemaLocation="opencms://opencms-xmlcontent.xsd"/>  

 

          <xsd:element name="Holidays" type="OpenCmsHolidays"/>

          

          <xsd:complexType name="OpenCmsHolidays">

                   <xsd:sequence>

                             <xsd:element name="Holiday"
type="OpenCmsHoliday" minOccurs="0" maxOccurs="unbounded"/>

                   </xsd:sequence>

          </xsd:complexType>

 

          <xsd:complexType name="OpenCmsHoliday">

                   <xsd:sequence>

                             <xsd:element name="Title" type="OpenCmsString"
/>

                             <xsd:element name="Duration"
type="OpenCmsString" />

                             <xsd:element name="Price" type="OpenCmsString"
/>

                   </xsd:sequence>

                   <xsd:attribute name="language" type="OpenCmsLocale"
use="required"/>

          </xsd:complexType>

 

          <xsd:annotation> 

                   <xsd:appinfo> 

                             <resourcebundle
name="com.bright.dtw.workplace"/> 

                             <mappings>

                                      <mapping element="Title"
mapto="property:Title" />

                             </mappings>

                             <validationrules>

                                      <rule element="Price" regex="[0-9]*"
message="Price should be a number." />

                             </validationrules>     

                   </xsd:appinfo> 

          </xsd:annotation>  

</xsd:schema>

 

 

 

3. You can search over the index using the OpenCms search API, something
like this to search on Price=50:

sQuery = "Price: 50";

                   CmsSearch search = new CmsSearch();

                   search.setIndex("Holiday");

                   search.setDisplayPages(k_iMaxPages);

                   search.setMatchesPerPage(iNumResults);

                   search.setSearchPage(iPage);

                   

                   Sort sort = new Sort("SortTitle");

                   search.setSortOrder(sort);

 

                   search.init(cmsObject);                          

                   search.setQuery(sQuery);                       

                   results = search.getSearchResult();

 

etc

 

Search on Google for 'Lucene query syntax' to find more detail on how to
form the query string in your search code.

Hi

You need to map the elements of the structured content item to Lucene
fields, using OpenCms search field configuration.

alkacon-documentation/documentation_search/configuration_fields.html

The configuration can be done in Administration > Search option, or see the
config file opencms-search.xml.
