query - {exclusion_list_query_1, ..., exclusion_list_query_n}
|
- in which
query is a wild card search, e.g. ab*; or a fuzzy search, e.g. constitution~2 - if
query does not have a wild card or fuzzy term, a syntax error will be returned - in which
exclusion_list_query_n is a - term, e.g.
apple, - wild card search, e.g.
ab*, or app[a-m]e, or app?e, - fuzzy search, e.g.
constitution~2
- Empty term lists are allowed and will be ignored
- A search query
a* - { } will return all terms in a dictionary starting with a letter 'a'
- Terms in the exclusion list should be separated by commas, otherwise a syntax error will be returned
- Wild card query within the exclusion list cannot have an exclusion list
- A search query
a* - {abc*, avocado} is valid, but a search query a* - {avocado, ap* - {apple}} isn't allowed because ap* has an exclusion list with term 'apple', thus, an error will be returned: 'Error 4150: Unexpected nested exclusion list'.
- Terms and wild card queries within exclusion lists may be quoted
- A search query
a* - {abc*, avocado} and "a*" - {"abc*", "avocado"} will return identical results
- A wild card query with wild card queries in the exclusion lists might take longer than just the original wild card query
- A search query
a* - {abc*, *do} might take longer than a search query a*
- An unquoted wild card query with an exclusion list must have a white space between the wild card query and the '-' symbol indicating introduction of the exclusion list. A quoted wild card query can omit the white space.
- A search query
a* - {avocado} is correct because '-' is preceded by a white space - A search query
a*-{avocado} will be parsed as a single search term: "a*-{avocado}". Usually no results will be found. - A search query
"a*"-{avocado} is correct because the wild card query is bordered by double quotes
