+/**
+ * Although lunr provides the ability to create queries using lunr.Query, it also provides a simple
+ * query language which itself is parsed into an instance of lunr.Query.
+ *
+ * For programmatically building queries it is advised to directly use lunr.Query, the query language
+ * is best used for human entered text rather than program generated text.
+ *
+ * At its simplest queries can just be a single term, e.g. `hello`, multiple terms are also supported
+ * and will be combined with OR, e.g `hello world` will match documents that contain either 'hello'
+ * or 'world', though those that contain both will rank higher in the results.
+ *
+ * Wildcards can be included in terms to match one or more unspecified characters, these wildcards can
+ * be inserted anywhere within the term, and more than one wildcard can exist in a single term. Adding
+ * wildcards will increase the number of documents that will be found but can also have a negative
+ * impact on query performance, especially with wildcards at the beginning of a term.
+ *
+ * Terms can be restricted to specific fields, e.g. `title:hello`, only documents with the term
+ * hello in the title field will match this query. Using a field not present in the index will lead
+ * to an error being thrown.
+ *
+ * Modifiers can also be added to terms, lunr supports edit distance and boost modifiers on terms. A term
+ * boost will make documents matching that term score higher, e.g. `foo^5`. Edit distance is also supported
+ * to provide fuzzy matching, e.g. 'hello~2' will match documents with hello with an edit distance of 2.
+ * Avoid large values for edit distance to improve query performance.
+ *
+ * Each term also supports a presence modifier. By default a term's presence in document is optional, however
+ * this can be changed to either required or prohibited. For a term's presence to be required in a document the
+ * term should be prefixed with a '+', e.g. `+foo bar` is a search for documents that must contain 'foo' and
+ * optionally contain 'bar'. Conversely a leading '-' sets the terms presence to prohibited, i.e. it must not
+ * appear in a document, e.g. `-foo bar` is a search for documents that do not contain 'foo' but may contain 'bar'.
+ *
+ * To escape special characters the backslash character '\' can be used, this allows searches to include
+ * characters that would normally be considered modifiers, e.g. `foo\~2` will search for a term "foo~2" instead
+ * of attempting to apply a boost of 2 to the search term "foo".
+ *
+ * @typedef {string} lunr.Index~QueryString
+ * @example Simple single term query
+ * hello
+ * @example Multiple term query
+ * hello world
+ * @example term scoped to a field
+ * title:hello
+ * @example term with a boost of 10
+ * hello^10
+ * @example term with an edit distance of 2

What does MySQL plugin do? \u00b6 The Delphix MySQL Plugin can virtualize a single instance MySQL database and create multiple virtual copies as required. There are two modes of operation of the plugin based on how the MySQL dSource is created and kept in-sync with source database. Replication \u00b6 In the Replication mode, Delphix uses MySQL's built-in replication technology to keep the Delphix dSource in-sync with the MySQL source databases. Creation of the dSource requires a full backup of the source database(s) and there are two options to providing this backup. Delphix Managed Backup In this option, Delphix is provided with the required information to take a full backup of the source database. User Provided Backup In this option, user provides Delphix with an existing full backup. Delphix initializes the staging database using the full backup and configures the staging database as a replicated slave of the source database. MySQL Replication keeps the data in the staging database in-sync with the source. Manual Ingestion \u00b6 In the Manual Ingestion mode, the data in Delphix dSource is managed manually by the end users. Delphix creates a seed MySQL staging database which can be managed via Delphix. The end user assumes the responsibility of keeping the data in the staging database in-sync with the source database. Where to Start? \u00b6 By now, you must have an overall idea of what is possible with the MySQL plugin. Before you can get started with virtualizing your MySQL databases, there are some pre-requisites you need to take care of. Please visit the Pre-Requisites page for more details.
