example: select a facet
example: select a facet

This catalog has a faceted search interface that allows you to filter searches by selecting collection-specific criteria. For instance, a user could browse language resources by language, language family, linguistic data type, geographic region, or format type. These "facets" appear in lists on the right side of the page.

Search Strategies

Begin with the search box: One way to begin the search process is to search for a keyword using the "Search for language resources" box. You can then apply one or more of the facets to narrow down the list of results.

Begin with the facets: Another way to begin is to select a facet first, which will bring up all the language resources that share that facet. You can apply additional facets and enter keywords in the "Search for language resources" box to narrow the results.

Search for related items:If the search results contain a language resource that meets your research interests, and you would like to see more like that one, click on the title to bring up the resource description page. Then select your specific criteria of interest in the "Find Related Information" column on the right, and click "go".

About faceted searching

  • Each selected facet will be displayed at the top of the list under "Currently Used Filters." Selecting an additional facet will run a search for a new criterion within the existing set of results, and, along with a new list of results, the facet options will change to reflect the records and facets available in the new results set.
  • To see additional options for any given facet, click on the word "browse" in that individual facet's box. This will bring up a list of all the options for that facet. The numbers in parentheses are the counts of available records for the given facet value in the current results set. Click on any facet to add it to your search criteria.
  • To remove a selected facet at any stage in the process, click the red x-dot () next to that facet in the "Currently Used Filters" list at the top of the column.
  • To remove all facets at any stage in the process, click the home icon (), which is beside the text query box.

Advanced Search Form

A link leading to the "Advanced Search" interface appears in the navigation links at the left side of the site. The advanced search allows for keyword searching within particular fields and combinations of searches in multiple fields. Enter a single term, multiple terms, or a phrase in the first search box. In each search string, truncation may be used (see below). The first drop-down menu gives a choice of searching for all of the terms, any of the terms, or all of the terms in order as a phrase. The second drop- down menu gives the choice of fields for searching. Up to six more search strings may be added using the Boolean operators in the drop-down menu to the left of the additional search boxes. To leave the "Advanced Search" interface, use the "Search Collection" box at the top of the page or follow the link for "Collection Home."

Expert search

The search box at the top of the page will return relevance ranked results based on the terms you enter. More complex keyword searches are also possible using various features of the search box:

1. You can use the Boolean operators AND, OR, NOT to combine search terms.

  • syntax AND morphology will return only results with both words
  • syntax OR morphology will return results with either word
  • syntax NOT morphology will return results that contain the first word but not the second

Note: The operators (AND, OR, NOT) must be entered in all caps.

2. Use quotes to search for specific phrases like

  • "historical syntax"
  • "picture dictionary"

3. Use the truncation * to find variations on your search term

  • phonolog* will find: phonology, phonologies, phonological, phonologie (French)
  • lexic* will find: lexicon, lexicons, lexica, lexical, lexicostatistical, as well as related words in other European languages
