key features:
	searching
		search multiple corpora simultaneously
		build search lists with according to a variety of criteria
			select passages by hand or via autofill boxes that know the structure of any text at any point
			search by date range
			add/exclude individual authors
			add/exclude individual author genres
			add/exclude individual works
			add/exclude individual work genres
			add/exclude individual passages
			add/exclude work spans ('books 1-2', e.g.)
			add/exclude individual author locations
			add/exclude individual work provenances
			include/exclude spuria
			include/exclude undateable works
			remove items from the list by double-clicking
			store and load search lists between sessions
			reset sessions to configurable defaults
		search syntax
			search with or without polytonic accents
				type accented words to make the search sensitive to accents
				type unaccented words and the search is not sensitive to accents
			wildcard searching via regular expressions
			phrase searching: "κατὰ τὸ ψήφιϲμα", etc.
			proximity searching:
				within N lines or words
				not within N lines or words
			lemmatized searches: look for all known forms of a word
			lemmatized searches can be combined with non-lemmatized proximity searches
			phrase searches can be combined with other types: phrase + phrase, phrase + lemmatized or phrase + word
		results
			results can be limited to a maximum number of hits
			results can be limited to one hit per author/work
			results can be sorted by name, date, etc
			can set amount of context to accompany results
	tools
		browser
			browse to any passage of your choice
			browse to any passage that occurs as a search result
			skim forwards or backwards in the browser
			click on words to acquire parsing and dictionary info for them
		dictionaries
			look up individual words in Greek or Latin
			customize dictionary output contents
			get a morphological analysis of a Greek or Latin word
			get per corpus counts of the use of the word and its derivatives
			get a weighted chronological distribution of the word's use: mostly 'early', etc.
			get a weighted distribution by top N genres: show if a word predominantly 'epic', etc.
			get a summary of uses, senses, phrases, and quotes
			reverse lookup: 'unexpected' returns ἀδευκήϲ, ἀδόκητοϲ, ἀδόξαϲτοϲ, ἀελπτία, ...
				by default results return in order of word frequency
			click to browse to passages cited in the lexical entries ('often' works)
			click to follow a 'cf.'
			flip forward/backwards through neighboring entries
		morphology tables
			see all extant forms arrayed by dialect, mood, voice, etc.
			use statistics present next to each form
				e.g., 2nd sg attic middle future indicatives are...
				ἀπολέϲηι (4) / ἀπολεῖ (181) / ἀπολέει (2) / ἀπολέϲει (181) / ἀπολέϲῃ (244) / ἀπολῇ (21)
			click to execute a follow-up search on any item
			toggles set the amount of detail to display
		text maker
			build a text of a whole work or subsection of a work
			for example see Xenophon, Hellenica as a whole or just book 3 or just book 3, chapter 4
			customize text output formatting
		index maker
			build an index for a whole author, work or subsection of a work
			for example see an index to all of Vergil or just the Aeneid or just Book 1 of the Aeneid
			index by word observed or by dictionary headword (if found...)
			sort index alphabetically or by number of hits
			click on index words to get lexical information [excessive index size will disable this]
			click on index passages to browse to that passage [excessive index size will disable this]
		semantic vectors
			calculate the relationship between words on any arbitrary search list using linear algebra
			various algorithms available:
				literal proximity
				word2vec nearest neighbors
				lsi matrix-similarity
				lda topic maps
			configurable settings for key variable like training runs and downsampling
			trim results by part of speech

local/contextual information
		searches give progress updates in percentage complete and time elapsed
		concordance builds give progress updates in percentage complete and time elapsed
		search lists can be inspected/hidden before execution
		local info on current author can be shown/hidden
		local info on genre lists can be shown/hidden
		show/hide the settings pane
		show/hide the complex criteria setter
		show/hide the complex search dialog boxes
		hover over interface items to get tooltips

misc
		restrict access via user/pass combinations
		accepts betacode input of greek (with or without accents):
			"MH=NIN A)/EIDE QEA\"
			"mh=nin a)/eide qea\"
			"mhnin aeide qea"
		search will attempt to choose the most efficient strategy for any given situation
		text layout in results/browser/text maker sensitive to shifts in font face and size
		text layout via CSS: possible to modify the style sheet to suit your own tastes
		optional highlighting of editorial insertions: {abc}, <def>, (ghi), [jkl]
		configurable defaults for most options
		configurable UI elements: hide features you will never use
		will display annotations to the original text
		unicode support of technical, rare, and exotic characters (that you can also search for: 𐆂,𐄒, 🜚)
		can find Coptic words and characters: 'ⲫⲓⲗⲟⲑⲉⲟⲥ', 'ϩανϭοϊ̈', etc.
		forward-compatible unicode: attempt to properly code characters which are not yet available in most fonts
		known unknowns: unhandled characters preserve their betacode messages in the metadata for future fixes
		debugging options can be enabled at launch time (see "./run.py -h")
        (optional) threading via helper extension
        (optional) websockets via helper extension
        (optional) semantic vectors via helper extension

```

HipparchiaServer typically runs from the command line within a python virtual environment

for example:

% ~/hipparchia_venv/bin/python3 ~/hipparchia_venv/HipparchiaServer/run.py

or, more tersely:

% run.py

Upon startup you will see something like:

![launch_image](https://raw.githubusercontent.com/e-gun/HipparchiaServer/stable/screenshots/successful_launch.png)

Note that `keyedlemmata` can take a while to load. You are ready for business when you see the last line that says `Running...`:

* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Then you aim your browser at http://localhost:5000 and you are ready to roll.

Alternately you can hook HipparchiaServer to something like nginx via uwsgi. That would create a different url

By default HipparchiaServer will not accept connections that do not originate from the host machine. It would be rather
unwise to expose this server to the whole internet. There are many elements to this unwisdom.

Let us only mention one of them: there are security checks inside Hipparchia, but many queries can be generated that would
consume vast computational resources. What would happen if 1000 people tried to do that to your machine at once?

Of course, most queries take <2s to execute. But servers live in the worst of all possible worlds.

Instructions on how to use Hipparchia can be found by clicking on the '?' button if you can make it to the front page.

```

minimum software requirements:

to launch HipparchiaServer
		python 3.6+
			flask
			psycopg2 or psycopg2-binary
			websockets
		postgresql 9.6+

to run the vectorizing functions
		python 3.6+
			cython
			scipy
			numpy
			gensim
			sklearn
			pyLDAvis
			matplotlib
			networkx
			umap-learn

to properly interact with HipparchiaServer via a browser
		jquery
		jquery-ui
		js-cookie
		a fully stocked unicode font [Arial, DejaVu, Noto, Roboto, ...]

HipparchiaThirdPartySoftware can provide jquery, etc.
	HipparchiaExtraFonts can provice Noto, etc.
	
	javascript must be enabled in the browser
	the browser must accept cookies if you wish to save searches

```

See **Hipparchia[Platform]** for autoinstallers and/or installation recipies for your operating system. Hipparchia can be installed on 
**BSD**, **Linux**, **macOS**, and **Windows**. The required fonts and JS libraries are available via **HipparchiaThirdPartySoftware** (https://github.com/e-gun/HipparchiaThirdPartySoftware)

Nevertheless, here are the project pages for the other dependencies:

jquery:
	http://jquery.com/download/

jquery-ui:
	http://jqueryui.com/download/

js-cookie:
	https://github.com/js-cookie/js-cookie/releases

`semanticvectors` are **not installed** by default. If you install them, you will also need 
to edit `./server/settings/semanticvectorsettings.py` to enable them: `SEMANTICVECTORSENABLED = 'yes'`

Note also that different types of vector search need to be individually enabled within the configuraiton file. 
The default installation has them all set to `no`. So you will need to edit at least one of them and set it to `yes`.
