/**
* SimpleQuery is a query parser that acts similar to a query_string query, but
* won't throw exceptions for any weird string syntax. It supports
* the following:
*
* - '{@code +}' specifies {@code AND} operation: {@code token1+token2}
*
- '{@code |}' specifies {@code OR} operation: {@code token1|token2}
*
- '{@code -}' negates a single token: {@code -token0}
*
- '{@code "}' creates phrases of terms: {@code "term1 term2 ..."}
*
- '{@code *}' at the end of terms specifies prefix query: {@code term*}
*
- '{@code (}' and '{@code)}' specifies precedence: {@code token1 + (token2 | token3)}
*
- '{@code ~}N' at the end of terms specifies fuzzy query: {@code term~1}
*
- '{@code ~}N' at the end of phrases specifies near/slop query: {@code "term1 term2"~5}
*
*
* See: {@link SimpleQueryStringQueryParser} for more information.
*
* This query supports these options:
*
* Required:
* {@code query} - query text to be converted into other queries
*
* Optional:
* {@code analyzer} - anaylzer to be used for analyzing tokens to determine
* which kind of query they should be converted into, defaults to "standard"
* {@code default_operator} - default operator for boolean queries, defaults
* to OR
* {@code fields} - fields to search, defaults to _all if not set, allows
* boosting a field with ^n
*
* For more detailed explanation of the query string syntax see also the online documentation.
