Only documents that contain all words from your search request are shown. The more words you put in your search request, the more precise the search becomes.

When you do not know how to spell a word, write it as it sounds and use a phonetic search. Results will include words that sound like what you typed.

Use double quotes to search for an exact phrase. This eliminates documents where the words occur but are not next to one another or are in the wrong order.

The NEAR operator finds documents where the query terms are within 16 words of each other.

The NEXT operator finds documents where the query terms are next to each other.

Use the language:XX operator (where XX can be en, fr, ge, etc.) to narrow the search to documents of a specific language.

The intitle: operator allows you to search for a word or a group of words found within the title of a document.

The before: operator restricts a search to documents created or modified before a given date (in the YYYY/MM/DD format)

The after: operator restricts a search to documents created or modified after a given date (in the YYYY/MM/DD format)

Prefix search allows you to find documents based on the beginning of a word.

The site: operator is used to focus a search on a particular web site.

Use the + (plus) operator to search for the exact word in a document. This operator also allows you to search for link words (like "the", "a", "of", "or", "and") which are ignored by default.

The - operator allows you to remove from the search results all documents containing a specific word or expression.

The OPT operator allows you to specify a term without making its presence mandatory for a document to appear in the search results.

The AND and OR operators can be combined to match documents against advanced boolean logic.

Exalead supports regular expression patterns. Patterns are introduced by a slash ('/') character. Within a regular expression, '.' is a special character that can represent any character, '*' stands for character repetition, '|' stands for 'or', and parenthesis are used to group characters. '?' is placed the end of a character group to make it optional.
