To enter a query, type in a few descriptive words and press the Enter key or click the Search button. You will obtain a list of relevant results.
The search uses sophisticated text-matching techniques to find pages that are both important and relevant to your search. For instance, analyses not only the target page, but also the pages linking into it to determine the value of the target page for your search. The search also favours pages in which your query terms appear close to each other.
Note: Encrypted, viewable PDF documents are converted to HTML for indexing. However, the HTML code is not displayed.
A single spelling suggestion is returned with the results for queries where the spell checker has detected a possible spelling mistake.
The spell checker feature is context sensitive. For example, if the query submitted is "george bash", "george bush" is suggested as an alternative query. However, "shell bash" would not return an alternate query suggestion of this nature.
Note: At present, the spell checker supports only US English.
Synonyms are words that have the same or similar meanings. On the results page, they are displayed as "Other Suggested Searches".
The Sort by Date feature sorts and presents your search results based on date. The date of each file is returned in the results. Results that do not contain dates are displayed at the end, sorted by relevance.
By default, only returns pages that include all of your search terms, so there is no need to include "and" between terms. For example, to search for engineering product specification documents, enter:
To broaden or restrict the search, include fewer or more terms.
The search supports the logical "OR" operator. To retrieve pages that include either word A or word B, use an uppercase "OR" between terms. For example, to search for an office in either London or Paris, enter:
Every search result lists one or more excerpts from the web page to display how your search terms are used in context on that page. In the excerpt, your search terms are displayed in bold text so that you can quickly determine if that result is from a page you want to visit.
Searches are not case sensitive. All letters, regardless of how you enter them, are understood as lower case. For example, searches for "george washington," "George Washington," and "George washington" all return the same results.
The search automatically ignores some common words and characters known as "stop words", which include most pronouns and articles. Automatically excludes words like ‘where’ and ‘how’ from your search terms, as well as certain single digits and letters. Stop words tend to slow down your search without improving the results. However, if you wish to include words in the search would otherwise ignore, use the "+" operator in front of stop words or enclose the entire phrase in quotation marks. Make sure to leave a space before the plus sign.
For example, if you are searching for version I of an annual report:
You can also include the "+" operator in phrase searches.
To provide the most accurate results, the search does not use "stemming" or support "wildcard" searches. Rather, searches for exactly the words that you enter into the search box.
For example, searching for "airlin" or "airlin*" will not yield "airline" or "airlines." If in doubt, try both forms. For example: "airline" and "airlines".
Since the search only returns web pages that contain all of the words in your query, refining or narrowing your search is as simple as adding more words to the search terms you have already entered. The refined query returns a specific subset of the pages that were returned by your original broad query.
You can exclude a word from your search by putting a minus sign ("-") immediately in front of the term you want to exclude. Make sure to leave a space before the plus sign.
For example, the search:
will return pages that do not contain the word "musica".
You can search for phrases by adding quotation marks. Words enclosed in double quotes ("like this") appear together in all returned documents. Phrase searches using quotation marks are useful when searching for famous sayings or specific names.
Certain characters serve as phrase connectors, which work just like quotes: joining the search words. For example, the search:
is treated as a phrase search even though the search words are not enclosed in double quotes. The search recognises hyphens, slashes, periods, equal signs, and apostrophes as phrase connectors.
You may also narrow searches by restricting queries in certain ways.
| Restrict Search | Query Syntax | Example |
|---|---|---|
| to a specific location on your site | allinurl; allintitle; inurl; intitle | allinurl:mjusticia help see Advanced Operators for details |
| to specific domains | site: | site:mjusticia.gob.es see Advanced Operators for details |
| to specific file types like Excel spreadsheets, PDF docs, etc. | filetype: | filetype:pdf |
Directory Restricting
To restrict the directories searched, enter a URL that drills down through the directory structure to the directories or files to be searched. For example, the query [google.com/manual/] restricts the search to everything at the manual level. If the trailing slash is not included, as in [google.com/manual], then all subdirectories are also searched.
The Search supports several advanced operators, which are query words with special functions. A list of the advanced operators with their explanations are provided below.
The query [cache:] shows the cached version of the web page. For instance, [cache:www.mjusticia.gob.es] shows the cached page of
Ministry of Justice homepage.
Note: There can be no space between cache: and the web page URL.
If you include other words in the query, those words will be highlighted within the cached document. For example, [cache:www.www.mjusticia.gob.es press releases] shows the cached content with the words "press" and "releases" highlighted.
Note: There can be no space between "site:" and the domain.
For example, to find all links to Stanford's main page, enter:
Note: There can be no space between "intitle:" and the following word.
Also, putting [intitle:] in front of every word in your query is equivalent to putting [allintitle:] at the front of your query. For instance, [intitle:mjusticia intitle:search] is the same as [allintitle: mjusticia search].
Note: The [allinurl:] operator works on words, not URL components. In particular, it ignores punctuation. Thus, [allinurl: foo/bar] restricts the results to pages with the words foo and bar in the URL, but does not require that the words be separated by a slash within that URL, that they be adjacent or that they be in that particular order. There is currently no way to enforce these constraints.
Note: There can be no space between "inurl:" and the following word.
Note: [inurl:]operator works on words, not URL components. In particular, it ignores punctuation. Thus, in the query [mjusticia inurl:foo/bar], the inurl: operator affects only the word "foo", which is the single word following the inurl: operator, and does not affect the word "bar ". The query [mjusticia inurl:foo inurl:bar] can be used to require both "foo" and "bar" to be in the URL.
Also, putting [inurl:] in front of every word in your query is equivalent to putting [allinurl:] at the front of your query. For example, [inurl:mjusticia inurl:search] is the same as [allinurl: mjusticia search].
