Devices, systems, and methods for tokenizing search attributes and terms of a search query for an index-based search. A method may include receiving, by a search service of a provider network, a first search query to search a first searchable document set, the first search query including a first search term in a first language; applying a first tokenization rule to identify the first search term in the first search query; determining that the first search term is in the first language; applying a second tokenization rule to tokenize the first search term based on the first search term being in the first language; causing a launch of a search instance by a managed compute service of the provider network, the search instance to execute a search function for a keyword-based text search using the tokenized first search term.

Techniques for visual data preparation are described. An interactive visual data preparation service provides a user with a graphical user interface that presents values from a sample taken of a dataset along with statistical information associated with those values. A user uses the graphical user interface to test out various transformations to the sample dataset by applying transformations and viewing near-immediate results of those transformations as applied to the sample. The desired set of transformations is represented as a recipe object, which can be used to perform data preparation against the overall dataset or other datasets on behalf of the user or other users.
