A modern text indexing library for go. (this is a mirror of the github repository)

![]() previous approach used SetEventCallback method which allowed you to change the callback, unfotunately that also included times after the goroutines were started and potentially firing the callback. checking lock on this would be too expensive, so instead we go for an approach that allows callbacks to be registered by name during process init(), then upon opening up an index a string config key 'eventCallbackName' is used to look up the appropriate callback function. also, since this string config name is serializable, it fits into the existing bleve index metadata without any new issues. |
