Working with Solr: Creating Collections and Indexing them

Solr in ColdFusion needs some basic code change in creating ,indexing and searching a collection.

Creating Collection:
While creating a collection ColdFusion requires an attribute 'engine' to indentify a collection as Solr or Verity. Default value of 'engine' is verity. Defining the attribute 'engine' is one time activity, for indexing and search ColdFusion will automatically identify the collection type.

< cfcollection action="create"

collection="mysolr"
key="#expandpath('.')#"
type="path"
engine="solr">

This will create a solr collection named 'mysolr'. also there is no need to define language and categories at the time of creation of collection,language can be defined at the time of indexing a collection.


Indexing Collection:

Indexing a Solr collection is similar to Verity.

< cfquery name="getCourses" datasource="cfdocexamples">
SELECT * FROM COURSES
< /cfquery>


< cfindex action="Update"
      query="getCourses"
      collection="mysolr"
      type="Custom"
      key="Course_ID"
      title="Courses"
      body="Course_ID,Descript"
      custom1="Course_Number">

For indexing a Solr collection in some other languages than English, language attribute can be defined in <> tag.

Solr supports following languages:

• Danish

• Dutch

• Finnish

• French

• German

• Italian

• Norwegian

• Spanish

• Portugese

• Russian

• Swedish

• Chinese

• Japanese

• Korean

• Czech

• Greek

• Thai


However, Solr supports indexing documents in any language. If the document has a language (for example, Arabic) not listed above, it can still index the content(as english), but stemming will not be available in search.
