Search with operators
To have all documents mentioning an exact phrase, you can use double quotes.
Example: “Alicia Martinez’s bank account in Portugal”
To have all documents mentioning all or one of the queried terms, you can use a simple space between your queries or 'OR'. You need to write 'OR' with all letters uppercase.
Example: Alicia Martinez
Same search: Alicia OR Martinez
To have all documents mentioning all the queried terms, you can use 'AND' between your queried words. You need to write 'AND' with all letters uppercase.
Example: Alicia AND Martinez
To have all documents NOT mentioning some queried terms, you can use 'NOT' before each word you don't want. You need to write 'NOT' with all letters uppercase.
Example: NOT Martinez
Parentheses should be used whenever multiple operators are used together.
Example: ((Alicia AND Martinez) OR (Delaware AND Pekin) OR Grey) AND NOT parking lot
If you search faithf?l, the search engine will look for all words with all possible single character between the second f and the l in this word. It also works with * to replace multiple characters.
Example: Alicia Martin?z
Example: Alicia Mar*z
If you search for similar terms (to catch typos for example), you can use the tilde symbol. "The default edit distance is 2, but an edit distance of 1 should be sufficient to catch 80% of all human misspellings. It can be specified as: quikc~1" (source: Elastic).
Example: quikc~ brwn~ foks~
Example: Datashare~1
"While a phrase query (eg "john smith") expects all of the terms in exactly the same order, a proximity query allows the specified words to be further apart or in a different order. In the same way that fuzzy queries can specify a maximum edit distance for characters in a word, a proximity search allows us to specify a maximum edit distance of words in a phrase." (source: Elastic).
Example: "fox quick"~5

If you are looking for documents that:
contains term1, term2 and term3
and were created after 2010
you can type in the search bar:
term1 AND term2 AND term3 AND metadata.tika_metadata_creation_date:>=2010-01-01
Explanations:
'metadata.tika_metadata_creation_date:' means that we filter with creation date
'>="'means 'since January 1st included'
'2010-01-01' stands for January 2010 and the search will include January 2010
For other searches:
'<' will mean 'strictly after (with January 1st excluded)'
nothing will mean 'at this exact date'
You can use other metadata fields using the following model: metadata.tika_metadata_[and copying the field's name here].
To find the list of existing metadata fields, go to a document's 'Tags and details' tab, click 'Show more details' and refer to this list:
