15. A system, comprising: a token mapping datastore storing token mapping data that associates a plurality of strings with corresponding tokens, wherein the token mapping datastore is included in a first computing environment associated with a first trust level; a whitelist token mapping datastore storing whitelist token mapping data that associates a subset of the plurality of strings with the corresponding tokens, wherein the whitelist token mapping datastore is included in a second computing environment associated with a second trust level; a first computing device in communication with the token mapping datastore, the first computing device configured to execute computer-readable instructions that cause the first computing device to: generate tokenized information that includes one or more tokens that correspond to one or more strings of the plurality of strings; and send the tokenized information to be stored in the second computing environment; and a second computing device in communication with the first computing device and the whitelist token mapping datastore, the second computing device configured to execute computer-readable instructions that cause the second computing device to: receive a search request to search for a file that includes one or more search terms; for the one or more search terms that are included in the whitelist token mapping data, retrieve the corresponding token from the whitelist token mapping datastore; for the one or more search terms that are not included in the whitelist token mapping data, send a request that the first computing device retrieve the corresponding token from the token mapping datastore; search for a tokenized version of the file that includes the one or more tokens corresponding to the one or more search terms; identify, in the tokenized version of the file, one or more tokens that are included in the whitelist token mapping data; replace the identified one or more tokens with the corresponding string from the whitelist token mapping data, to generate an at least partly detokenized version of the file; and provide the at least partly detokenized version of the file in response to the search request.

The system of claim 15 , wherein: the token mapping datastore includes the token mapping data for one or more of the plurality of strings that include sensitive data; and the whitelist token mapping datastore includes the whitelist token mapping data for one or more of the plurality of strings that do not include the sensitive data.
