What is Metasearch

Metasearch is a single point of access to the journal titles of Opinion Archives.

How to Search

You can specify simple phrases, or complex boolean queries, and you can limit searches to certain fields if desired. The following search fields are available:


hello kitty

ti="hello kitty" and date=1999

ti=hello kitty and (au=smith or au=jones)

Quotes and parenthesis are optional, but can be used to disambiguate complex queries, or queries that contain words like 'and' which can be mistaken for operators.

If your result set is large, it will be truncated by the metasearch engine. Try to make queries as precise as possible. If your result set is large, you can use the facets on the left to narrow the search until you find what you are looking for.

Delimiting Results By Journal Titles or Facets

Metasearch will search all titles by default with the search terms you enter. If you wish to limit your search to one or more selected titles, please check the box adjacent to the title.

You can specify your search criteria further by using the facets on the left under the titles. That way you can limit results to a certain subject or author.

The subject facet is represented as a 'tag cloud', meaning that a term in a larger font indicates a subject that appears more frequently in the current set of results.

Sorting Results

You can sort results by Relevance, Title, or Date (descending or ascending). Relevance ranking takes place on the client side according to the popular TF-IDF algorithm.

Response Time

Pazpar2 is a high-performance metasearch system, designed to make results available to the user from the target databases as quickly as possible. That means that as soon as results become available, they are displayed. However, the performance of individual back-end databases are outside of our control. What this means is that if one database is slow to respond, the system will keep waiting until all results have been returned. However, during this time, the user can browse the available results, change the sort order, start new searches, and generally use the system normally.


This metasearch interface is based on Pazpar2 from Index Data.
