Azure search hit-highlighting and match delimiter

阅读更多关于 Azure search hit-highlighting and match delimiter

问题 I am using hit-highlighting in azure search. It works fine but I want to fine tune it a bit. Say, a field has the following value: "It uses period as the delimiter. If not, please clarify" If I search for "please" I will get a highlight hit on that field, e.g.: "If not, please clarify" If I search for "period" I will get a highlight hit on that field, e.g.: "It uses period as the delimiter." After trying it with several examples it seems that it uses period (".") as a

We have a web application that uses SQL Server 2008 as the database. Our users are able to do full-text searches on particular columns in the database. SQL Server's full-text functionality does not seem to provide support for hit highlighting. Do we need to build this ourselves or is there perhaps some library or knowledge around on how to do this? BTW the application is written in C# so a .Net solution would be ideal but not necessary as we could translate. Expanding on Ishmael's idea, it's not the final solution, but I think it's a good way to start. Firstly we need to get the list of words
