More results returned via API vs Front End (MAUDE Search Tool)

[CAMarq]

I'm unsure if this is the right way to contact about this query, I have posted a question on Stack Exchange without response, my apologies if posting here is incorrect!
Stack Exchange post: (https://opendata.stackexchange.com/questions/21801/more-results-returned-via-api-vs-front-end)

"I am using the openFDA API to pull results for adverse events based on brand name and date range.

This is the URL that I am using: https://api.fda.gov/device/event.json?search=device.brand_name:premierpro%20exofinfusion+AND+date_received:[2019-01-01+TO+2024-12-01]&limit=1000

The intended filter is for data range: 2019-01-01 to 2024-12-01, brand name: premierpro exofinfusion.

The openFDA API returns 3 results ("MW5114259" "MW5115284" "MW5115902"), meanwhile the site returns a single record ("MW5115284").

If I look for two records missing in the front end query, they do appear to exist and would fit into the criteria. Is there something I'm misinterpreting or an API/Front-End functionality to be considered?

Thank you!

EDIT: I'm using the following site: accessdata.fda.gov/scripts/cdrh/cfdocs/cfmaude/search.cfm'"

Thank you so much in advance for your help and guidance.

Hi @CAMarq, we can’t easily explain the discrepancy, as we have no visibility into how the MAUDE Front-End search is implemented. It’s managed by a different team at the FDA and does not use the openFDA API for search, instead relying on their internal databases.

It seems, however, that the Front-End search applies more restrictive criteria for matching search terms. openFDA performs full-text search, identifying matches even when terms appear in a different order (e.g., "premierpro exofinfusion" matches "EXOFINFUSION PREMIERPRO MESH"), whereas the Front-End does not.
