An acquisition expert who
wanted to find clutch units for turbines could add the keyword “turbine” and
select a logical AND search — which would find those parts that had both of the
terms somewhere in their description.
In this example, the system found over 32,700 parts for the “turbine” term, but when combined
with the previous search for “clutch”, the final number of parts that meet both criteria were 3. The results
within the lower table.
the back end, the
search engine established sets
of records that matched the queries, and
AND’ed the two sets to get the resulting set
of records that matched both
criteria. The query
completed very quickly due to the specialized indexes used in the
server. The customer could also have selected an OR’ed
list — which provided the list of parts that matched either of the criteria
selected, instead of both criteria.
From this combined collection, the customer could use the powerful linking
capabilities of the underlying
software to show additional part information, by linking to other databases.
To see detailed information about the part, we selected one of the
records in the lower table and double-clicked it, bringing up contract, pricing,
procurement and other information provided through common cross-references.
The screen to the left shows the part’s description and other specifications —
just one of many screens that we could link to from the primary screen.
