this process beyond supports the following use cases:

• terminologies holds:
• nothing: it will search internal and external
• only local stuff: it will search only local
• only external stuff: it will search only external
• mixed acronyms: it will check which one is local and which one is external befor performing the search
• undefined acronyms: they will be ignored

---

• if format or match_type is set
• if an external service was listes with its acronym in terminologies and it doent support the match_type or the format, it will be skipped
• otherwise it will perform the search

---

• if first_hit is true:
• if no terminologies are given, the process will be cancelled
• otherwise i will break after the first not empty search result
