Abstract: Embodiments of the present disclosure provide techniques for using an inverted index in a pipelined search query. A field searchable data store is provided that comprises a plurality of event records, each event record comprising a time-stamped portion of raw machine data. Responsive to the reciept of an incoming search query, the search engine accesses an inverted index, wherein each entry in the inverted index comprises at least one field name, a corresponding at least one field value and a reference value associated with each field name and value pair that identifies a location in the data store where an associated event record is stored. Once the inverted index is accessed, it can be used to identify and search a subset of the plurality of event records, wherein the subset comprises one or more event records with corresponding reference values in the inverted index.

Abstract: Embodiments of the present disclosure provide techniques for performing searches of event records by leveraging reference values in an inverted index. A method of searching comprises accessing a query associated with a first set of event records in a field searchable data store, each event record comprising a time-stamped portion of raw machine data. The method further comprises evaluating the query and generating results for the query by accessing an inverted index, wherein each entry in the inverted index comprises at least one field, a corresponding at least one field value and a reference value that identifies a location in the field searchable data store where an associated event record is stored. The method further comprises performing a search to filter out a second set of event records and retrieving the second set of event records from the field searchable data store using reference values in the inverted index.

Abstract: A single chain drive is disclosed that includes a drive sprocket, a drive motor, idler sprockets, front and rear axle sprockets, and a single chain. The drive motor rotates the drive sprocket, which rotates the idler sprockets, which rotate the single chain, which rotates the front and rear axle sprockets. The drive sprocket can be a lantern gear with covers, and pins that connect the cover, and the idler sprockets can have teeth that mesh with the pins between the covers of the drive sprocket. A drive shaft can couple the drive motor and drive sprocket, and an integrated parking brake can prevent rotation of the drive shaft when engaged. A chain case with lubricant can enclose the drive sprocket, idler sprockets, chain, and axle sprockets. The drive sprocket, idler sprockets and axle sprockets can be sized to provide a desired gear reduction.

Abstract: A method for dislodging exhaust gas deposits from an exhaust gas recirculation (EGR) cooler (26) associated with an engine includes the steps of providing at least one on-board gas source (S) for providing a gas (G) at a superatmospheric pressure, and placing the EGR cooler in fluid communication with the gas source through a supply conduit (44, 144). The supply conduit (44, 144) includes at least one valve (V) that is selectively operable to a closed condition closing the supply conduit and to an open position opening the supply conduit. The method also includes the step of operating the at least one valve (V) from the closed condition to the open condition to allow the superatmospheric gas (G) to flow through the supply conduit (44, 144) to the EGR cooler (26).

Abstract: A portable storage device can comprise a web page confidence module and a device controller. The web page confidence module may be configured to receive a web page address and determine a trust level status associated with the web page address. The device controller may be configured to indicate a trust level status based on the trust level determination.

Abstract: A portable storage device includes a web page confidence module and a device controller. The web page confidence module may be configured to receive a user trust setting, receive a webpage address and determine a trust level status associated with the web page address based in part on the user trust setting. The device controller may be configured to indicate a trust level status based on the trust level determination.

Abstract: A system for shredding data in NAND memory can comprise a database and a device controller. The database may be configured to store the data. The device controller may be configured to receive a shred command, overwrite the data within at least a portion of the NAND memory pursuant to the shred command, generate a flag that indicates the at least the portion of the NAND memory was overwritten, and store the flag in a secure storage.
