I finally have an explanation, I post it here for future reference : The cause was a combination of :
1) /select request handler has default with the spellcheck ON and few spellcheck options ( such as collationQuery ON and max collation tries set to 5) 2) the firstSearcher has a warm-up query with a lot of terms Basically when opening the searcher, I found that there was a thread stuck in waiting and that thread was the one responsible for the collation query. Basically the Searcher was never finishing to be opened, because of the collation to be calculated over the big multi term warm-up query. Lesson Learned : be careful with defaults in the default request handler, as they may be used by other components ( then just user searches) Thanks for the support!
