The index search CAN and SHOULD be shared across threads.
索引搜索CAN和应该在线程之间共享。
The trick is deciding when to refresh your searcher with a new snapshot of the index.
诀窍是决定何时刷新搜索与索引的新快照。
I wrote an article showing how I coded sharing a searcher across threads while at the same time making sure that the searcher was always using an up-to-date index.
我写了一篇文章,展示了我如何编码跨线程共享搜索者,同时确保搜索者总是使用最新的索引。
I'm not saying my solution is the best for everybody - I don't think it would be good for a website with a huge number of searches going on - but it's working fine for my low volume application.
我并不是说我的解决方案对所有人来说都是最好的 - 我认为这对于搜索量很大的网站来说并不好 - 但它对我的小批量应用程序来说效果很好。

You can index and search concurrently, but the changes you make to the index will not be visible to the searcher till you re-create the searcher. Searcher will have the snapshot of the index when you created the searcher object.
您可以同时进行索引和搜索,但在重新创建搜索器之前,搜索器将无法看到您对索引所做的更改。在创建搜索器对象时,Searcher将获得索引的快照。
