Instructions:
- Look for this line in dspace.cfg: ##### Fields to Index for Search #####
- 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
- 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.
- If you want to add an entirely new search field, you will also have to modify Messages.properties (see Change page text (JSP) ) 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.)
- Perform the steps in Re-index DSpace .
- 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.
