This is a metasearch system. It is a single point of access to the following institutions:
You can specify simple phrases, or complex boolean queries, and you can limit searches to certain fields if desired.
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. The following search fields are available:
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 as a mechanism to narrow and disambiguate the search until you find what you are looking for.
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.
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.
