KEEP

KEEP is used to place selected records in an auxiliary set, numbered S0 (set zero). You can KEEP chosen records from various sets within your search, including sorted sets, to create a customized set of final search results.

You can use KEEP with:

• To KEEP an entire set:

?keep s2
   S0  32 S2

• To specify the item numbers from a set to be kept:

?keep s3/1,3-5,8
   S0  5 S3/1,3-5,8

• To use KEEP with accession numbers:

?keep 09130265
   S0  1 09130265

• To use a semicolon (;) to stack KEEP commands:

?keep 09130265;k 09120449
   S0  1 09130265
   S0  2 09120449

If no set number is specified after the KEEP command, KEEP defaults to the last item TYPEd or DISPLAYed. If no TYPE or DISPLAY command has been entered, the KEEP command defaults to the last set number.

• To default to the last item displayed or to the last set number if no items have been displayed:

?keep
   S0  32 S2

You must be connected to the database in which the records are stored in order to put those records into set S0. In OneSearch, the following options are available:

KEEP Sn FROM <file number(s)>
KEEP Sn/<items> FROM <file number(s)>
KEEP Sn/<items> FROM EACH

FROM is not required when you use the KEEP command in OneSearch, unless you are searching and KEEPing accession numbers (e.g., KEEP <accession no.> FROM <file number>).

• To use KEEP in a OneSearch:

?keep s2 from 636
   S0  137 S2 FROM 636

?keep s5/1-12 from 484
   S0  15 S5/1-12 FROM 484

?keep s3/1-5 from each
   S0  10 S2/1-5 FROM EACH

KEEP can be used in conjunction with the TYPE command to browse through records and choose specific items to later DISPLAY, TYPE, or PRINT. After you have created a set containing your final search results, enter TYPE Sn/n <range or record number> (where n is a short format or single display code). You can look at more records by entering a TYPE command that displays other records in the set. Once the record(s) is displayed, it can be rejected or selected with the KEEP command and stored for later use in set S0.

Note: You can TYPE, DISPLAY, PRINT, or SORT set S0, and you can use it in subsequent SELECT commands in the search strategy. However, you cannot use set S0 in a SearchSave strategy because the KEEP command cannot be SAVEd, so set S0 will not be recreated when the SearchSave is later activated.
