An entity using a computing device can upload searchable data to a network service to be indexed and stored. The data can include a plurality of data fields, each data field having one or more associated values. The network service can analyze the data fields and their respectively associated values to determine data field types for the data fields and search options to be enabled for the data fields. Based at least in part on the data field types and the search options, the network service can generate a search index configuration/schema. Based at least in part on the generated search index configuration/schema, the network service can generate a search index for the data. In some embodiments, the network service can also convert the data into a format compatible with the search index.
