Creation of a database of court decisions on the website

You need to use a website that runs on Joomla 1.5. Create a search for court decisions built into the general template of the site (you can write a module (mainly) or without it). The system you create should be automatically updated and be an analog, but not a copy of sites such as:
Texto oculto -

The source of information and the replenishment of databases for the above sites is Texto oculto.
All court decisions included in the database must be linked to federal laws and codes, the current version of which must be uploaded to the site through Texto oculto (by removing the pop-up text (hints), the relevant article from the law).

Preliminary assessment of documents in the database: 70-80 million documents. This means that the site should not use MySQL databases. Previous 2 attempts to pump such a volume into the database gave an unsuccessful result. It is possible that each court document should be on the server in the format *txt. The database and the system should not give a significant load on the server and the site, including be designed for simultaneous operation.

The system should have a common (one search bar) and advanced search (as here: Texto oculto) to documents. Ideally, it would be to create a flash map of the Russian Federation through which you could search for documents on the territory (for example, as here: [hide:guest]http://www.sudrf.ru/index.php?id=300 or here https:///rospravosudie.com/research/map_any.html?f1=https:/rospravosudie.com/vidpr-ugolovnoe&m1=10&f2=httttack:/graf=htvos:/s:/smodulem2/com, by means of integration into each social network, by means of the following a legal system:10/simage/s/s/s/simage/s/s/s/s/s/simage.com, which must be automatically integrated into the system.com.commid/s.com.com. The title of the page of the document with the judicial act and links to it, the module of brief news on the judicial system and court decisions (news are uploaded from third-party sites with a link to them, an analogue of Yandex news) The site should be associated with the integration of users with joomla, registration in which should be divided into 2 types of users (user and lawyer). Accordingly, registered users can click on the kunena forum integrated with joomla.

The system must create files on the server sitemap files and be optimized for search engines (the name of the page of the document with the court decision should contain the name court. (a) decision).
