Search

ARIADNE searches the full text of every article, review and comment, and finds people. The search runs on the ARIADNE indexer (the service that reads the blockchain and builds what the website shows). It reads the texts from IPFS, the storage network where articles live, and keeps only those that match their fingerprint on the blockchain (DECISIONS D-120, D-121). Reading and searching need no wallet.

Open it from Search in the main menu, or from the search field of the feed. On TestNet: https://ariadne.press/testnet/search. Press / anywhere on the page to jump back to the search field.

The three tabs

Tab	Searches	Each result shows
Articles	title, abstract, keywords, the text, the authors (address, verified ORCID name and iD), field names, DOIs and CID	title, matched passages, type, status, seal, fields, authors, date, votes, reviews, comments, “cited by N”, DOI, number and version
Reviews and comments	the text of every review, comment and reply	the passage, its kind (a reply to a review says so), recommendation, author and article
People	verified ORCID names, ORCID iDs and the beginning of addresses	name or address, activity and reputation

When you have typed a query, each tab shows how many results it has, so you can see at once whether your words appear in reviews or people rather than in articles. Results come in pages of 20.

Writing a query

Accents and case do not matter, and words are matched by their stem: “sleeping” also finds “sleep”.

You type	It finds
sleep memory	both words, in any order (every word is required)
"memory consolidation"	the exact phrase
sleep -dream	“sleep” without “dream”
sleep OR dream	either word
neuro*	words that begin with “neuro”
title:sleep	the word in one part only
alice.algo, author:ADDRESS	articles by that author (an NFD name is turned into its address)
doi:10.5281/zenodo.123 or a bare DOI	the article that declared that DOI
cid:bafy…	the article that has a version with that CID
#12 (or id:12)	article number 12

The parts you can limit a word to are title:, abstract:, keyword:, body: (the text), author: (a name or an address) and field: (field names, DOIs and CID). A few synonyms work too: summary:, tag:, text: and by:. A word before a colon that is not one of these is searched as an ordinary word, and the page says so.

Wildcards inside words

You type	Meaning
wom?n	? is exactly one letter or digit: woman, women
*ology	* is any number of letters or digits, within one word: biology, psychology
neur*sis	neurosis, neuropsychosis

A * at the end of a word is the ordinary prefix search above. A ? that ends a word is read as a question mark (“what is sleep?”). A wildcard needs at least two letters besides the ? and *.

Regular expressions

For anything more precise, write a regular expression (JavaScript syntax) between slashes: /memor(y|ies)/, /^sleep/. It can be limited to one part (title:/^the /) or excluded (-/x/). Expressions and wildcards are tested on the texts without accents, case ignored, and their matches are marked in the results. Reviews, comments and people accept them too.

Limits, because an expression can take a very long time on many texts:

• at most 200 characters per expression, and 5 wildcards or expressions per query;
• each search may spend 2 seconds on them; past that the page says the expression “takes too long over this many texts: make it more specific, or add words or filters”;
• all searches together may spend 20 seconds per minute on them; past that the page says they “are busy: try again in a minute”.

A broken expression matches nothing, and the page says why. Searches without wildcards or expressions have no such limit.

Filters

Filters are in the Filter panel beside the results. On screens narrower than 1 024 pixels the panel starts closed unless a filter is in use; open it with Filter. Each group of filters starts folded and stays open while one of its filters is in use. Every option shows how many results it would give with the other filters you chose. Ticks and dates apply at once; typed values apply with Enter or Apply.

Article filters

Three quick switches sit above the results:

• Seal: Any, or Peer-reviewed: only articles that hold the Peer-reviewed seal now.
• Reviews: Any, Reviewed, or Not yet.
• DOI: Any, With, or Without (only DOIs whose record does not contradict them count).

The filter panel has these groups:

Group	Options
Area	the six areas of fields; an article matches by its main or second field
Field	the fields that have results; Main field only ignores the second field
Type	article, notes, amendment, dataset, replication
Status	preprint, under review, closed version, disputed, retracted. Retracted articles are hidden unless you choose them.
Published	one year with a click, or From and Until dates
Reviews and votes	Reviewed: accept (or minor revision, major revision, reject): articles that received such a review; Vote weight at least; Comments at least
DOI and ORCID	Verified DOI; Authors with a verified ORCID iD
People	Author (address or name.algo) with Submitter only; Reviewed by; Commented by; Author’s ORCID iD; Only by people I follow (with a wallet connected)
Language and licence	from the article headers, when any article declares them
More	Keywords (comma-separated, all required); Revised (more than one version); Has amendments; Amends article #; Content checked; Updated from and Until (date of the last version)

Each filter in use appears as a chip above the results; click a chip to remove it, or Clear all filters.

Review and comment filters

Kind (Reviews, Comments and replies), Recommendation, and Where and who: Written by, On article #, Field of the article, From and Until.

People filters

Role (Authors, Reviewers, Commenters), With a verified ORCID iD, and Reputation in a field, which also shows each person’s reputation in that field.

Sorting

Tab	Sorts
Articles	Best match (with a query), Top, Newest, Oldest, Most voted, Most reviewed, Most discussed, Recently updated, Most cited on ARIADNE
Reviews and comments	Best match, Newest, Oldest, Most voted
People	Best match, Reputation, Publications, Reviews written, Recently active

Without a query, articles are sorted by Top, the score of the feed: the weight of the votes divided by (age in days + 2) raised to the power 0.8, so that recent, well-voted articles come first. Most cited on ARIADNE counts citations from other ARIADNE articles that are not retracted (see Citations and Thread Score).

A search is a link

Everything you chose (query, tab, filters, sort, page) is in the page address. Copy it to share a search, bookmark it, or come back to it later; the browser’s Back and Forward buttons walk through your changes. For example, recent peer-reviewed articles that mention a phrase:

https://ariadne.press/testnet/search?q=%22memory+consolidation%22&sealed=true&sort=new

The page works without scripts, too.

Save from the results

Every article in the results has a small Save button. It opens the same dialog as on the article page, where you tick private or public lists (see Lists and bibliographies).

Suggestions and recent searches

While you type, the field suggests titles (which open the article), keywords and fields (which become filters) and people (who open their profile). With the field empty it offers your last 8 searches. These are kept in this browser only; Forget recent searches clears them.

When nothing is found

Try fewer or other words, or a word ending in * to match its beginning (neuro* finds “neuroscience”). Remember that retracted articles are searched only when you choose that status. If another tab has results for your words, the page offers a button to it.
