Modify search fields

Files:

• dspace/config/dspace.cfg
• dspace-source/jsp/local/search/advanced.jsp
• dspace-source/config/language-packs/Messages.properties

Instructions:

1. Look for this line in dspace.cfg: ##### Fields to Index for Search #####
2. Beneath it you will see several lines like this:

   search.index.1 = author:dc.contributor.*

   search.index.2 = author:dc.creator.*

   search.index.3 = title:dc.title.*

   search.index.4 = keyword:dc.subject.* 

   search.index.5 = abstract:dc.description.abstract 

3. Add another search.index.# line to the bottom. If you just want to add a different Dublin Core (

   dc

   ) field to one of the existing "named indices", use the models above as a guide. If you wish to specify a different metadata schema, replace

   dc

   with the other metadata schema's name.
   • The "name" to the left of the colon (e.g. author, title, keyword, etc) is important. In the above example, a search on "author" is specified to search all Dublin Core (

     dc

     )

     contributor

     and

     creator

     fields. Whereas, a search on "abstract" only searches the

     dc.description.abstract

     field.
4. If you want to add an entirely new search field, you will also have to modify Messages.properties (see Change+page+text) to add a user-friendly label for it, and the advanced-search JSP (advanced.jsp) to add an appropriate

   <option>

   element, as below:

   <option value="author" <%= field1.equals("author") ? "selected=\"selected\"" : "" %>><fmt:message key="jsp.search.advanced.type.author"/></option> 

   • The "value" attribute of your

     <option>

     element should correspond to the name of one of your search indices (e.g. author, title, keyword, etc.)
5. Perform the steps in Re-index+DSpace.
6. Perform the steps in Rebuild+DSpace.

Notes:

• In DSpace, the most confusing concept regarding search fields is the keyword search.
• In the basic search boxes (as seen below), any terms entered are searched for anywhere within any of the search indices (i.e. any of the

  search.index.#

  fields in dspace.cfg), or the full text of the document (if it is full-text indexable). These search boxes perform what most refer to as a keyword or keyterm search.
  

• However, to make things a little confusing, you'll notice a keyword search index listed in dspace.cfg:

  search.index.4 = keyword:dc.subject.*

  This (rather inappropriately named) index is actually used during subject specific searches (hence the

  subject.*

  ). It does not have any control over a normal keyword search that is run from the basic search box in DSpace.
