OHIF plugin case insensitive patient name search/filtering with Orthanc

Hi,

I’m having a bit of a time trying to get the Orthanc OHIF plugin to be case insensitive for patient name filtering in the studies list.

For testing purposes, I have a test study with a patient name “Test, Tester” uploaded w/ S3 storage backing this.

My orthanc.json config has “Dicomweb”: { “QidoCaseSensitive”: false } set and also “OHIF” : { “DataSource” : “dicom-web” } set (which is default?)

I’ve primarily been testing with jodogne/orthanc-plugins:1.12.8, but also today with 1.12.9

When searching/filtering on “test” in the OHIF Study List, it yields no results, but “Test” will display the entry.

Looking a bit more at the traffic, when searching/filtering for Patient Name “test” from OHIF, the Orthanc “/dicom-web/studies?PatientName=test…” endpoint is indeed returning the JSON with the result correctly (“Test Tester”) to OHIF, but OHIF is not showing it in the study list UI.

I came across this thread:

> I thought the filtering happens client side when we looked at the code It o…nly happens if it's a static wado datasource, otherwise it calls the super method, we don't control or filter anything there, so it's all up to backend (orthanc in this case) what to return See here https://github.com/OHIF/Viewers/blob/a863808947f33a456e08f893c775dba9a46e4750/extensions/default/src/DicomWebDataSource/utils/StaticWadoClient.ts#L101-L123 ```js async searchForStudies(options) { if (!this.staticWado) { return super.searchForStudies(options); } const searchResult = await super.searchForStudies(options); const { queryParams } = options; if (!queryParams) { return searchResult; } const lowerParams = this.toLowerParams(queryParams); const filtered = searchResult.filter(study => { for (const key of Object.keys(StaticWadoClient.studyFilterKeys)) { if (!this.filterItem(key, lowerParams, study, StaticWadoClient.studyFilterKeys)) { return false; } } return true; }); return filtered; } ```

If I do a browser override of app-config.js (this is the only way I could figure out how to influence the variable) and set staticWado: false -then- OHIF displays the result that was returned from Orthanc when filtering on patient name “test” or “Test”/etc which is what I want. It now seems case-insensitive.

Since orthanc-ohif: f185306d615f Sources/app-config-system.js is appended at the end of app-config.js with staticWado: true hardcoded, I don’t know how to get this to work as the value cannot be set in the file “OHIF” { “UserConfiguration”: “ohif.js” } because the plugin’s hardcoded config is appended after the contents of ohif.js to generate the app-confg.js response.

If staticWado: true is indeed required, are there other settings I’m missing to get this to work as expected? I tried setting supportsFuzzyMatching : true, which is hardcoded as well, but that seemed cause even less functional filtering.

Thanks!
