What is the "Search all Tabs" add-on and how can I use it?

After installation, the extension adds a toolbar button to your browser. You can open the popup to search for any content in one of your existing tabs. The extension uses the indexing method to find the most relevant content that matches the user query. Like all search engines, this extension supports most of the search operators likeORandAND.

When the popup gets opened, the extension injects a small JS code into all open tabs to fetch all the text-based contents. Then it passes these contents to the indexing engine. At this point, the extension is ready to perform your search queries over its internal database. When a search has matching entries, these results are populated to the popup with preview and link to the actual content. To easily distinguish each search result, the extension appends the favicon of the tab to the search entry. The matching words are also highlighted in the previewed snippet. When an entry is matched with what you are looking for, click on the title and the extension focuses the relevant tab for you. Also, the content that is shown in the snippet will be selected. You can use the number next to each entry to activate the tab without using your mouse button as well. The indexer script that this extension uses a CPP library called Xapian (converted to pure JS). It is a powerful indexing engine that performs indexing and searching on really large databases. It is probably the search engine behind most of your native tools too.

Why does the extension require indexing each time the popup gets opened?

Because it cares about your browser performance and your privacy. This extension uses a non-persistent background script which basically is unloaded when the popup is closed. Also, the indexed database is stored in your browser memory and get destroyed when the popup is closed to free up the memory. Note that the indexing is blazing fast so there is no need to save the file for later use. Just open the popup and type the searching query. The engine that this extension uses is capable of indexing very large databases.

Can I use this extension to search local text files?

If you have no local tool that supports search operators and keywords, you can use your browser! The extension's indexing engine only works on the browser tabs. If you need to search on local files, drag them to the browser window to let the files get opened in your browser where the extension can read their content. Also note that if you are using a Chromium browser, you will have to allow the extension to have access to the local files in the extension manager (file://). So when the files are opened as browser tabs and the extension has permission to access them, you can open the popup and search within these local files. To limit your search results to local files appendURL:file://to the search query

Can I use any keyword to reduce the number of shown matches?

This extension supports the following keywords. You can use them to extend to reduce the number of matches. To use a keyword, appendkeyword:queryto your query * hostname: the hostname of the document that got indexed (e.g. www.google.com for https://www.google.com) * title: the title of the web page or the title of the document element. If a frame provides its own title, that title gets used instead of the parent's title. * mime: the mime type of the document. For web pages it istext/html. * url: URL of the document. For frames, the URL is invisible to the user, but the extension indexes them too. * date: the last modified date of the document in YYYYMMDD format. * filename: is equal tolocation.pathnameof each URL. * language: the page's language tag. If no tag is provided, "english" is used. See the list of supported languages in the relevant FAQ. To match a particular language uselanguage:englishfor instance. * keyword: the comma-separated list of keywords that are placed in the meta tag of the document. * description: the meta description tag of the document For instance to search for a book in a google.com tab that contains "physics" keyword in the meta description use:url:google AND keyword:physics. You can useurl:google OR keyword:physicsto extend your search results to tabs with google in their URL and or "physics" in their meta description.

What are the supported languages?

At this point the extension supports language parsing for "arabic", "armenian", "basque", "catalan", "danish", "dutch", "earlyenglish", "english", "finnish", "french", "german", "german2", "hungarian", "indonesian", "irish", "italian", "kraaij_pohlmann", "lithuanian", "lovins", "nepali", "norwegian", "porter", "portuguese", "romanian", "russian", "spanish", "swedish", "tamil", "turkish".

Note that upon searching a new query, the extension detects the most possible input language of the query and uses that language to parse the query

Why the number of documents that is shown in the popup is more than the number of opened tabs of my browser?

Each frame element inside a page is considered a separate document with its own URL and meta information. Since iframes are frequently used inside web pages, usually the document number is more than the total number of your browser tabs.

Why when I open the popup, the extension already has a query in its search box?

To ease the usage, the extension looks for selected text in the current page and uses it as its initial query.

What is the meaning of the number that is shown on the right side of each search entry?

It is the percentage that this search entry matches with the user's query. 100% means that the query and the search result do have a 100 percent match.

What are the searching operators that I can use?

• AND and NOT: will return results that contain both ‘term1’ and ‘term2’.

• XOR (exclusive OR): will return results that contain either ‘term1’ or ‘term2’, but not both.

• OR: will return results that contain either ‘term1’ or ‘term2’.

• Brackets: Change search ordering liketerm1 AND (term2 OR term3)

• NEAR: will return results where term1 is within 10 words of term2.

• ADJ: will return results where term1 is within 10 words of term2, but in the same order as in the query

• Phrases: According to the Xapian documentation a phrase surrounded with double quotes (like this: “my phrase”) will return results that match everything containing “that exact phrase”

  Note that you can combine search operators with keywords too.
