Abstract: A method for document similarity analysis. The method includes generating a reference document content identifier for a reference document, including identifying frequently occurring terms in reference document content, encoding each frequently occurring term in a term identifier and combining the term identifiers to form the reference document content identifier associated with the reference document. The method also includes obtaining at least one document similarity value by comparing the reference document content identifier to a set of archived document content identifiers stored in a document repository.

Abstract: A method for servicing document search requests. The method includes receiving, by a document management service, a document search query from a requesting user, and injecting, into the document search query, a user access vector. The user access vector specifies, for the requesting user, access control lists that are associated with the requesting user. The method further includes identifying, in a document repository, documents that match the document search query with the injected user access vector. A matching document requires a match of terms in the search query with terms in the matching document, and a match of at least one access control list specified in the matching document and at least one of the access control lists specified in the user access vector.

Abstract: A nanobioremediation method is for soil in a high-concentration polycyclic aromatic hydrocarbon (PAH)-contaminated site. The method includes adding a carbon nanomaterial and a base fertilizer to soil in a high-concentration PAH-contaminated site, evenly broadcast sowing alfalfa seeds to the contaminated soil, and keeping the soil moisture content at 60% of the field moisture capacity, and when the alfalfa grows to the flowering or maturity stage, harvesting and removing the plants from the contaminated soil.

Abstract: In general, in one aspect, the invention relates to a method for servicing requests. The method includes receiving, from a client system, a request comprising a query, where the query includes a first plurality of terms. The method further includes generating, using a thesaurus library, a related query including a second plurality of terms, where at least one term in the second plurality of terms is present in the first plurality of terms. The method further includes issuing the query to a content repository to obtain a first result, issuing the related query to the content repository to obtain a second result, processing the first result and the second result to generate a final result, and providing the final result to the client system.

Abstract: A method for managing a document search index. The method includes obtaining indexing terms for documents in a document repository to generate search index fragments, storing the search index fragments in a document search index, and constructing a hierarchical structure from a first set of stored search index fragments. The selected first set of search index fragments is arranged by size, in the hierarchical structure. The method further includes selecting, based on a minimal size, a second set of stored search index fragments from the hierarchical structure, merging the second set of stored search index fragments to obtain a larger search index fragment, storing the larger search index fragment in the document search index, and serving at least one search request using the larger search index fragment.

Abstract: A method for document search in a structured document repository. The method includes obtaining a document search query from a client, obtaining location constraints for documents to be identified in a structured document repository based on the document search query, identifying, in a document search index associated with the structured document repository, a document that matches the search query and the location constraints, and providing information associated with the identified document to the client.

Abstract: A method for servicing document search requests. The method includes receiving, by a document management service, a document search query from a requesting user, identifying, in a document repository, by the document management service, a document that matches the search query, and obtaining a permission level by the document management service, from an access control cache, based on a combination of the requesting user and an access control list required by the document. The access control cache is located on the document management service, and the access control cache is populated using content in an access control repository located on a repository server, separate from the document management service. The method further includes making a determination that the permission level is sufficient and based on the determination, returning the document to the requesting user, as a search result.
