Abstract
Describes and evaluates the proximity search facili ties in external online systems and in-house retrieval software Discusses and illustrates capabilities, syntax and circum stances ot use. Presents measurements of the overheads re quired by proximity for storage, record import time and search time The search strategy narrowing effect of proximity is illustrated by Recall and Precision test results. Usage and problems lead to a number ot design ideas for better imple mentation. some based on existing Boolean strategies. one on the use of weighted proximity to automatically produce ranked output A comparison of Boolean, quorum and proximate term pairs distance is includedKeywords
