1. SISU SEARCH \- INTRODUCTION
.BR

.BR
.B SiSU
output can easily and conveniently be indexed by a number of standalone
indexing tools, such as Lucene, Hyperestraier.

.BR
Because the document structure of sites created is clearly defined, and the
text object citation system is available hypothetically at least, for all forms
of output, it is possible to search the sql database, and either read results
from that database, or just as simply map the results to the html output, which
has richer text markup.

.BR
In addition to this
.B SiSU
has the ability to populate a relational sql type database with documents at
an object level, with objects numbers that are shared across different output
types, which make them searchable with that degree of granularity. Basically,
your match criteria is met by these documents and at these locations within
each document, which can be viewed within the database directly or in various
output formats.

.SH
2. SQL
.BR

.SH
2.1 POPULATING SQL TYPE DATABASES

.BR
.B SiSU
feeds sisu markupd documents into sql type databases PostgreSQL[^1] and/or
SQLite[^2] database together with information related to document structure.

.BR
This is one of the more interesting output forms, as all the structural data of
the documents are retained (though can be ignored by the user of the database
should they so choose). All site texts/documents are (currently) streamed to
four tables:

.BR
  * one containing semantic (and other) headers, including, title, author,
  subject, (the Dublin Core...);

.BR
  * another the substantive texts by individual \"paragraph\" (or object) \-
  along with structural information, each paragraph being identifiable by its
  paragraph number (if it has one which almost all of them do), and the
  substantive text of each paragraph quite naturally being searchable (both in
  formatted and clean text versions for searching); and

.BR
  * a third containing endnotes cross\-referenced back to the paragraph from
  which they are referenced (both in formatted and clean text versions for
  searching).

.BR
  * a fourth table with a one to one relation with the headers table contains
  full text versions of output, eg. pdf, html, xml, and ascii.

.BR
There is of course the possibility to add further structures.

.BR
At this level
.B SiSU
loads a relational database with documents chunked into objects, their
smallest logical structurally constituent parts, as text objects, with their
object citation number and all other structural information needed to construct
the document. Text is stored (at this text object level) with and without
elementary markup tagging, the stripped version being so as to facilitate ease
of searching.

.BR
Being able to search a relational database at an object level with the
.B SiSU
citation system is an effective way of locating content generated by
.B SiSU
. As individual text objects of a document stored (and indexed) together with
object numbers, and all versions of the document have the same numbering,
complex searches can be tailored to return just the locations of the search
results relevant for all available output formats, with live links to the
precise locations in the database or in html/xml documents; or, the structural
information provided makes it possible to search the full contents of the
database and have headings in which search content appears, or to search only
headings etc. (as the Dublin Core is incorporated it is easy to make use of
that as well).

5.1 SEARCH \- DATABASE FRONTEND SAMPLE, UTILISING DATABASE AND SISU FEATURES,
INCLUDING OBJECT CITATION NUMBERING (BACKEND CURRENTLY POSTGRESQL)

.BR
Sample search frontend <http://search.sisudoc.org> \ [^3] A small database and
sample query front\-end (search from) that makes use of the citation system,
.I object citation numbering
to demonstrates functionality.[^4]

.BR
.B SiSU
can provide information on which documents are matched and at what locations
within each document the matches are found. These results are relevant across
all outputs using object citation numbering, which includes html, XML, LaTeX,
PDF and indeed the SQL database. You can then refer to one of the other outputs
or in the SQL database expand the text within the matched objects (paragraphs)
in the documents matched.

.BR
Note you may set results either for documents matched and object number
locations within each matched document meeting the search criteria; or display
the names of the documents matched along with the objects (paragraphs) that
meet the search criteria.[^5]

.TP
.B \ sisu \ \-F \ \-\-webserv\-webrick
\ builds \ a \ cgi \ web \ search \ frontend \ for \ the \ database \ created
\

.BR
The following is feedback on the setup on a machine provided by the help
command:

.BR
  sisu \-\-help sql


.nf
  Postgresql
    user:             ralph
    current db set:   SiSU_sisu
    port:             5432
    dbi connect:      DBI:Pg:database=SiSU_sisu;port=5432

    current db set:   /home/ralph/sisu_www/sisu/sisu_sqlite.db
    dbi connect       DBI:SQLite:/home/ralph/sisu_www/sisu/sisu_sqlite.db
.fi

.BR
Note on databases built

.BR
By default, \ [unless \ otherwise \ specified] databases are built on a
directory basis, from collections of documents within that directory. The name
of the directory you choose to work from is used as the database name, i.e. if
you are working in a directory called /home/ralph/ebook the database SiSU_ebook
is used. \ [otherwise \ a \ manual \ mapping \ for \ the \ collection \ is \
necessary]

.SH
5.2 SEARCH FORM

.TP
.B \ sisu \ \-F
\ generates \ a \ sample \ search \ form, \ which \ must \ be \ copied \ to \
the \ web\-server \ cgi \ directory \

.TP
.B \ sisu \ \-F \ \-\-webserv\-webrick
\ generates \ a \ sample \ search \ form \ for \ use \ with \ the \ webrick \
server, \ which \ must \ be \ copied \ to \ the \ web\-server \ cgi \ directory
\

.TP
.B \ sisu \ \-Fv
\ as \ above, \ and \ provides \ some \ information \ on \ setting \ up \
hyperestraier \

.TP
.B \ sisu \ \-W
\ starts \ the \ webrick \ server \ which \ should \ be \ available \
wherever \ sisu \ is \ properly \ installed \

.BR
The generated search form must be copied manually to the webserver directory as
instructed

.SH
6. HYPERESTRAIER
.BR

.BR
See the documentation for hyperestraier:

.BR
  <http://hyperestraier.sourceforge.net/>

.BR
  /usr/share/doc/hyperestraier/index.html

.BR
  man estcmd

.BR
on sisu_hyperestraier:

.BR
  man sisu_hyperestraier

.BR
  /usr/share/doc/sisu/sisu_markup/sisu_hyperestraier/index.html

.BR
NOTE: the examples that follow assume that sisu output is placed in the
directory /home/ralph/sisu_www

.BR
(A) to generate the index within the webserver directory to be indexed:

.BR
  estcmd gather \-sd \ [index \ name] \ [directory \ path \ to \ index]

.BR
the following are examples that will need to be tailored according to your
needs:

.BR
  cd /home/ralph/sisu_www

.BR
  estcmd gather \-sd casket /home/ralph/sisu_www

.BR
you may use the \'find\' command together with \'egrep\' to limit indexing to
particular document collection directories within the web server directory:

.BR
  find /home/ralph/sisu_www \-type f | egrep
  \'/home/ralph/sisu_www/sisu/.+?.html$\' |estcmd gather \-sd casket \-

.BR
Check which directories in the webserver/output directory (~/sisu_www or
elsewhere depending on configuration) you wish to include in the search index.

.BR
As sisu duplicates output in multiple file formats, it it is probably
preferable to limit the estraier index to html output, and as it may also be
desirable to exclude files \'plain.txt\', \'toc.html\' and
\'concordance.html\', as these duplicate information held in other html output
e.g.

.BR
  find /home/ralph/sisu_www \-type f | egrep
  \'/sisu_www/(sisu|bookmarks)/.+?.html$\' | egrep \-v
  \'(doc|concordance).html$\' |estcmd gather \-sd casket \-

.BR
from your current document preparation/markup directory, you would construct a
rune along the following lines:

.BR
  find /home/ralph/sisu_www \-type f | egrep \'/home/ralph/sisu_www/([specify \
  first \ directory \ for \ inclusion]|[specify \ second \ directory \ for \
  inclusion]|[another \ directory \ for \ inclusion? \ ...])/.+?.html$\' |
  egrep \-v \'(doc|concordance).html$\' |estcmd gather \-sd
  /home/ralph/sisu_www/casket \-

.BR
(B) to set up the search form

.BR
(i) copy estseek.cgi to your cgi directory and set file permissions to 755:

.BR
  sudo cp \-vi /usr/lib/estraier/estseek.cgi /usr/lib/cgi\-bin

.BR
  sudo chmod \-v 755 /usr/lib/cgi\-bin/estseek.cgi

.BR
  sudo cp \-v /usr/share/hyperestraier/estseek.* /usr/lib/cgi\-bin

.BR
  \ [see \ estraier \ documentation \ for \ paths]

.BR
(ii) edit estseek.conf, with attention to the lines starting \'indexname:\' and
\'replace:\':

.BR
  indexname: /home/ralph/sisu_www/casket

.BR
  replace: ^file:///home/ralph/sisu_www{{!}}http://localhost

.BR
  replace: /index.html?${{!}}/

.BR
(C) to test using webrick, start webrick:

.BR
  sisu \-W

.BR
and try open the url: <http://localhost:8081/cgi\-bin/estseek.cgi>

of this feature when demonstrated to an IBM software innovations evaluator in
2004 he said to paraphrase: this could be of interest to us. We have large
document management systems, you can search hundreds of thousands of documents
and we can tell you which documents meet your search criteria, but there is no
way we can tell you without opening each document where within each your
matches are found.
