摘要： Methods and systems to build and utilize a search infrastructure are described. The system generates index information components in real-time based on a database that is time-stamped. The system updates index information at a plurality of query node servers based on the index information components. A query engine receives a search query from a client machine and identifies search results based on the query and the index information. The system communicates the search results, over the network, to the client machine.

摘要： Using a processor, receiving, a query including a query image. A database is searched for a set of images similar to the query image, using a two-pass search. The results of the searching are then provided, the results including image members of the set of images similar to the query image. The first pass may be performed using a TF-IDF algorithm and the second pass ranks a predetermined number of results from the first pass by a best match algorithm or other type of algorithm. The type of second pass algorithm may be selectable by a user. If an end signal is not detected, a further two-pass search may be made based on a subsequent query having a subsequent query image. The subsequent query image may one of the results of the previous two pass search. A subsequent query image may change from an image of a product of a first product category to an image of a product of a second product category.

摘要： A circuit is arranged to pulse-width modulate the duty cycle of a power supply signal that is used to control the rotational speed of a fan in a temperature-controlled system. The control system includes an edge detector for monitoring a tachometer signal that is provided by the fan. The tachometer signal is monitored at a rate (e.g., one Hertz) that is substantially lower than the rotational speed of the fan. The control system also includes a timer for recording time intervals between selected edges of a monitored tachometer signal. The fan speed is determined from the recorded time intervals. The control system extends the duty cycle of the pulse-width modulated signal to ensure that the fan power remains stable over the period in which the tachometer signal is to be monitored. Maintaining fan power ensures the validity of the tachometer signal during the period that the fan power is maintained.

摘要： A method for performing a search of a plurality of documents for similarity to a query word includes retrieving a first document, and determining a number of occurrences of the at least one query word in the first document. Then, a next document is retrieved and a number of occurrences of the at least one query word in the next document is determined. The steps are repeated until each of the plurality of documents have been retrieved, and the number of occurrences of the at least one query word has been determined in each of the plurality of documents. The query word can include a plurality of query words, all of which are searched in each document, in turn, rather than being searched word by word in the whole collection of documents. The documents are then ranked according to the number of occurrences of the query words determined in each document, and a list of documents is produced according to the document ranking.

摘要： Methods and systems to search a data source based on compatibility via a specification are disclosed. The system receives a query from a buyer that includes keywords and identifies at least one keyword in the query as application information. The application information describes a first application. Next, the system infers the other keywords in the query as item information that describes a first part that is sought on a network-based marketplace. The first part is a component of the first application. Next, the system associates the application information with specification identifiers respectively for parts that fit the first application. Next, the system searches the data storage device to identify listings that respectively describe an item for sale on the network-based marketplace, the listings to include listing specification information that matches at least one of the specification identifiers. The listings further include listing item information that matches the item information.

摘要： A method for searching a document corpus for query terms includes generating a list of document terms including a term signature for each term based upon characteristics of a number of adjacent terms. The term signatures can be generated by generating a bit vector for each term within a predetermined adjacent number of terms from each document term, such as through application of a hash function. The bit vectors can then be combined to form the term signature. The word signature alternatively can be generated using one or more morphological properties of the terms. The predetermined adjacent number of terms can be the number of search terms minus one, and may precede, follow, or both precede and follow the document term for which the term signature is generated. A search signature is generated for the query terms excluding a reference term, based upon the predetermined characteristics. The term signature of the reference term is compared with the search signature, and an indication is provided when the term signature of the reference term and the search signature match.
