A ZBW Center Controller reported NOTAMs referencing runway closures were not displayed on their Enroute Information Display System. The Controller reported a flaw in the 'search filter' function which omits this information under certain circumstances.

Narrative

As an OJTI (Training Instructor) I was assigned to train at sectors. In the morning; these sectors are combined with the low sectors. We received a briefing that an aircraft inbound to PQI; an airport we provide approach clearances; had not yet been issued NOTAMs. The controller providing the relief briefing mentioned that there were runway closures when he looked earlier but it appeared they were open again. As the OJTI; I opened the NOTAMs on an adjacent Enroute Information Display System (ERIDs); not the sector in question; and I could see there were two runway closure NOTAMs. When checking the ERIDs at the sector in question; we saw no runway closure NOTAMs. To clarify when you open an approach plate; the NOTAMs are displayed below. The approach plate was open for the approach requested by the pilot so we could see the NOTAMs below and the runway closures were not included. Investigating further I finally noticed someone had typed '11' into the search field filter of the NOTAMs on the approach plate page. After testing; we removed the 11 and could then see the runway closure NOTAMs. In further testing; if you enter text into the search filter on the approach plate page; hit back on the ERIDs and re-enter the approach plate page; that filter will remain in place. Additionally; unless that text is cleared; any approach plate at any other airport will still include the search filter parameters.The text filter search button on the approach plate page of ERIDs should clear when exiting the approach plate page. The current functionality of ERIDs retaining the text in the search filter field could cause a controller to miss a NOTAM for a closed runway if they don't notice there is text entered into the search bar. In the interim; the search filed should be disabled or the work force should be briefed about this issue.
