| DialogWeb Help: Additional Index Searching |
Additional Indexes are a series of indexes representing the fields that can be searched but are not part of the Basic Index. Additional Indexes are searched using prefix codes. Specific fields and codes vary according to the database you are searching. The database Bluesheet contains a list of available fields and codes.
Common Additional Index fields and codes include:
| Prefix Code | Field Name | Example |
| AU= | Author | s au=johnson, r? |
| CO= | Company Name | s co=ford motor? |
| CS= | Corporate Source | s cs=(harvard and medicine) |
| DT= | Document Type | s dt=review |
| JN= | Journal Name | s jn=new york times |
| LA= | Language | s la=french |
| PD= | Publication Date | s pd=960412 |
| PY= | Publication Year | s py=1996 |
| SA= | Sales | s sa=>5m |
| UD= | Update | s ud=9999 |
Note:
If a prefix is not supported in a database, there will be no records in the search
results. Also, your search terms must be exact, including spacing and punctuation. For
example, if you enter s co=r j reynolds? (without the periods) and the
company name is indexed as r.j. reynolds (with the periods) no records will be
found. If your first SELECT statement returns 0
results, EXPAND the term to see the proper index
entry, for example, e co=r j reynolds.
