Within Trados Studio 2019:

I can get search results for the following: "Apple | Banana", and "|"

Within Translation Memory Api:

I can get search results for the following: "Apple | Banana", but searching for "|" returns 0 hits.

These are my search settings:

string searchFor = "|";
FileBasedTranslationMemory tm = new FileBasedTranslationMemory(TranslationMemoryPath);
int totalTmTranslationUnitCount = tm.LanguageDirection.GetTranslationUnitCount();
SearchSettings sdlSearchSettings = new SearchSettings();
sdlSearchSettings.Mode = SearchMode.ConcordanceSearch;
sdlSearchSettings.MinScore = 70;
sdlSearchSettings.MaxResults = totalTmTranslationUnitCount;
sdlSearchSettings.FindPenalty(PenaltyType.FilterPenalty);
SearchResults results = tm.LanguageDirection.SearchText(sdlSearchSettings, searchFor);

Question:

Any ideas on how to get hits on only the pipe character?
