A computer generates a modified list of search terms by adding synonyms of the search terms and terms that are related to the search terms to a list of search terms. The computer removes frequently used words from the modified list of search terms. The computer responds to a determination that a user has authorization to view a field of a document by adding to the modified list of search terms an encrypted version of a search term included in a list of search terms. A search using the modified list of search terms returns a result that identifies the document as a search result when either the unencrypted or the encrypted version of the search term is found in a list of index terms associated with the first document.

Providing access control for public and private document fields

A computer determines, based on a degree of authorization of a user, that a user has authorization to view a type of field. Based on the degree of authorization of the user, the computer generates a modified list of search terms by adding additional search terms to a list of search terms. The computer executes a search using the modified list of search terms. The computer identifies a search result that includes the first type of field which further includes a search term that is included in the modified list of search terms.

A method, system and computer program product implementing the method are provided to process a text search query in a collection of documents. A full posting index is generated for the documents in the collection. The full posting index comprises one or more first index terms and a full posting list for each first index term, enumerating the occurrences of the first index term in the documents. In addition to the full posting index, at least one additional posting index is generated for the documents. The additional posting index is related to a defined document part and comprises one or more second index terms and a restricted posting list for each second index term, enumerating all occurrences of the second index term in the document part of the documents of the collection. The text search query is performed using the additional posting index.
