Differences between PubEAST/PubWEST and Patent Public Search
Changes to system limitations
The character limit in PubEAST/PubWEST has been removed for Patent Public Search.
In addition, Patent Public Search can support additional usage of unlimited truncation (using $ vs $n).
Truncation limits:
Match limit: If an individual term in a query matches on more than 20,000 hits, Patent Public Search will not try to run the query.
-
Example: A$ and database
The term A$ matches more than 20,000 hit terms so the query will not execute.
Combinatorial limit: When the product of the numeric modifiers exceeds 125, Patent Public Search will not execute the query.
-
Example: A$32B$4
The numeric modifiers 32 and 4 multiplied together equals 128. This is greater than 125 and the query will not execute. -
Example: A$3B$5C$2D$3
The product of the numerical modifiers equals 90. The query will execute unless the term would match more than 20,000 hits.
