Restricting Searches




  • Total records
  • Holdings

Restrict by Year

The year field can be used either as number or as a text string.

  • Arithmetic operations < > <>(not equal) = <= >= all give the expected result
  • between 1995 and 1997 gives range of years inclusively
  • 2000 just finds 2000 (functionally equivalent to =2000)
  • 200 finds all years from 2000 to 2009
  • 1999-2000 would return any records with that in their year field (there are a few)
  • Booleans are not supported eg 2000 and 2003 returns nothing

Restrict by Journal

Journal names are included just as originally printed. As a result Animal Behaviour might also be found as Anim. Behav. or even An. Behav. For the moment, a single part of the name should be supplied (eg Behavio). This would match any of the above, but also other journals such as Behaviour. We will decide at some point whether to solve this by regularising the journal names throughout the database, or whether to introduce full boolean searches on journal titles. Any views welcome on how best to do this.

Restrict by Record Status

Record status gives editorial information about the quality of the information

  • 0 means nothing known that invalidates this record (ie its probably ok)
  • 3 means it was entered online, and has not yet been checked by an editor .
  • 5 means the data is suspect for some reason.

You MUST enter an operator for now: eg restrict to edited records put = 0 in the box; to get all nonzero status records put >0 in the box

Restrict by Accession date

To find records relative to the date in which they were appended to the database put > or <  followed by the date in the format dd/mm/yyyy.
= is a synonym for no operator at all, and will return records inserted on that date.
Use with circumspection - if you ask for all records inserted on a particular date the result may be a very large number.

Restrict by Record ID

Only really useful for Editors. If you notice a faulty record and report it please supply the Record ID. It is listed as 'Article #' in the record header.
