Searching encrypted data using encrypted contexts by performing at least the following: configuring a first encryption context that allows access to a first encrypted field, configuring a second encryption context that allows access to a second encrypted field, assigning the first encryption context to a first role and the second encryption context to a second role, assigning the first role to a first user account to allow the first user account to access the first encrypted field, assigning the second role to a second user account to allow the second user to access the second encrypted field, receiving a query request associated with the first user account for a search term, wherein the query request includes instructions to search for an unencrypted version of the search term and a first encrypted value of the search term that is based on the first encryption context.

Searching for encrypted data within a cloud based platform

Embodiments are provided for calculating improved search scores for records that exhibit supra-threshold slop distances. These embodiments include receiving a search string that includes two or more words and determining, based on the search string, search scores for a plurality of text-based records. Determining a search score for a particular text-based record includes: determining a slop distance for the search string within the particular text-based record; determining that the slop distance is greater than a threshold distance; responsive to determining that the slop distance is greater than the threshold distance, determining an augmented slop distance for the particular text-based record; and determining the search score based on the augmented slop distance. Determining the augmented slop distance includes: identifying two or more groups of words within the search string; determining, for each of the groups of words, group slop distances that are products of intra-group slop distances and missing word penalties.

Enhanced phrase scoring for textual search

Embodiments are provided that include receiving a search query that represents a particular table of a plurality of tables contained in a database and that includes an additional criterion. Records are contained within the tables, which are organized in a tree structure. An index of the database contains a plurality of entries, each corresponding to a respective record in the plurality of tables. A particular entry in the index includes a path string that is indicative of a location, within the tree structure, of a table that contains a record that corresponds to the particular entry. The embodiments also include determining whether the entries in the index satisfy the search query by: (i) determining that the path string of the particular entry begins with a further path string of the particular table, and (ii) responsively determining whether a particular record that corresponds to the particular entry satisfies the additional criterion.
