On-line STScI Preprints Search HELP Page

Search Help

Fielded searches:

Only the fields that should be searched have to be specified.
The search is case-insensitive, but only returns entries which contain a given keyword exactly. That is, searching for Spac will not find Space. To change this behavior, use a wildcard. A search for Spac* will find Space, Spacious etc.
Only trailing wildcards are expanded. A question-mark ? is not a wildcard.
By default, the search uses AND logic. That is, it looks for entries that contain keywords from the author field if given AND keywords from the title field if given etc. To search for entries that contain keywords from the author field OR keywords from the title, select OR logic. All fields are either AND-ed or OR-ed.
If multiple keywords are given for e.g. the title field, all entries are returned that contain either one word or the other or both. To search for both words as if they were a single keyword, use double quotes: "Interstellar Absorption". Wildcards are not expanded inside double quotes.
It is not possible to explicitly search on e.g. author fields that contain author1 and author2. The search will also return entries that contain either author1 or author2. However, since the matches are sorted according to their scores, entries that matched both authors will appear at the top of the list.
The scores reflect the relative relevance of the matched entries. Entries that match equally well are sorted according to their preprint number, with the most recent preprint first.
Searches are automatically weighed. Hits in the author field precede hits in the title field which in turn precede all other hits.

Full text searches:

This will search the .tex source files for unpublished preprints where available. Note that this imposes a strong bias on the search results.
The search syntax is identical to that of a single field in the fielded search described above.
