Full guide on how to search Reserves.

Finding in a nutshell

The most powerful and convenient way for searching in Reserves, especially for more complex queries, uses Reserves "query language". This language s actually quite simple, yet very powerful. The basic principle is to tell the system where (the field tag) it should find what (your criterion). E.g. to find all documents with `foo` in the title one would just use title:foo

This kind of searching becomes especially powerful in conjunction with the identifiers used throughout the system. E.g. to get all publications published in `Nature <London>`, which are usually quite cumbersome to fiddle out due to the title of the journal, one can easily employ it's journal id PERI:(DE-600)1413423-8 and use the src field tag as src:"PERI:(DE-600)1413423-8"

The required id can easily be retrieved form the Authorities. You may also want to use the search generator as an easy way to create the queries required to fill in your publications lists on the web.

The following field tags are available:

abstract:	abstract	affiliation:	affiliation	author:	author	authorcount:	author count
citedby:	cited by	coden:	coden	collaboration:	collaboration	collection:	collection

To answer complex questions you can build the necessary complex queries using

• boolean operators
  • AND (can also be written as +)
  • OR (also |)
  • NOT (also -)
• bracketing ()
• quotes:
  • ' ' for substrings
  • " " for exact strings
  • / / for regular expressions
• wildcard * for any characters
• field tags to restrict matches e.g. title, or person etc.
