Methods and systems to search a data source based on compatibility with an application. The system receives a first query that includes keywords and identifies at least one keyword in the first query as application information. The application information describes a first application. Next the system infers remaining keywords in the first query as item information that describe a first item that is sought on a network-based marketplace. The first item is a part that is compatible with the first application. Next, the system searches a data storage device to identify a first listing on the data storage device as matched. The first listing includes an item for sale on the network-based marketplace and listing item information that matches the item information in the first query. The first listing further includes listing application information that is matched based on the application information.

Systems and methods to configure a query language using an operator dictionary are described. The system receives, from a first user, a search query to search for document information in a database. The system determines that terms of the search query from the first user are in accordance with dictionary information that corresponds to the first user. The dictionary information includes a first list of compatible query operators. The system applies the search query to the index data structure in the database to identify the document information. The system sends an electronic interface to the first user that includes the document information.

System and methods to configure a query language using an operator dictionary

A method and a system to configure a query language using an operator dictionary are provided. Dictionary information that corresponds to a first user is generated. The dictionary information includes a first list of compatible query operators and a description of compatible data types that correspond to each operator in the first list of query operators. A search query to search for document information in a database is received from a first user. The database includes an inverted index. Terms of the search query from the first user are determined to be in accordance with the dictionary information that corresponds to the first user. The search query is applied to the inverted index in the database to identify the document information. The document information is sent to the first user.

A method and system to process a data search request. The system includes a query controller module to receive the data search request that includes constraints; a reduced constraint builder module to formulate a plurality of search definitions that are formulated to exclude at least one constraint; and a search engine to perform searches of a data source to generate search results and to utilize the search results to calculate counts of data items that respectively correspond to the search definitions. The query controller module communicates the counts of data items and the corresponding search definitions to a client machine. Each of the search definitions is formulated to include a constraint set.
