摘要： Subject matter described herein includes a multi-layer search-engine index. Accordingly, the search-engine index is divided into multiple indexes, each of which includes a respective set of information used to serve (i.e., respond to) a query. One index includes a term index, which organizes a set of terms that are found among a collection of documents. Another index includes a document index, which organizes a set of documents that are searchable. A computing device is used to serve the search-engine index (i.e., to analyze the index when identifying documents relevant to a search query). For example, a solid-state device might be used to serve the multi-layer search-engine index.

摘要： A computing device configurable as a wireless network access point that can be controlled from multiple applications. The computing device provides an interface through which applications may input commands to change the state of the access point. The interface responds to these commands and other events, such as association or disassociation of a wireless client, in a manner that does not disrupt the applications or devices using the access point. To determine an appropriate response to any event, the interface may maintain state information, including a count of the number of applications and/or wireless devices that have taken action indicating an operating state of the wireless access point.
