Can The Search Treat Non-ascii And Plain Characters Equally? (Doc ID 2182146.1)

Last updated on MAY 27, 2019

Applies to:

Oracle Healthcare Master Person Index - Version 2.0.0 and later
Information in this document applies to any platform.

Symptoms

Depending on country/region, non-ascii characters may be very common in names, e.g. 'Sample nÁme'.
Some external systems sending queries to OHMPI for patient details, may send in the name with the non-ascii characters and this will work fine.
However some systems may send in the request using plain characters, e.g. 'Sample nAme'. And they would still expect the match to be found.

By default:
1. The Alpha Search just does not find a match.
2. The Phonetic Search finds a match but deducts such a large amount from the Weighting Score that they will not be returned as a match.

Phonetic search is applying the weighting even more severely for some names.
E.g. assuming we have 'nÁme' as a name, if searching for 'nAme' a negative -4 Weighting for Name is returned as if it is completely incorrect.

Due to this issue, users could not use plain ASCII characters on name searching to find names containing diacritics with a minimal weight loss.
