Line of Light

You view a range of pages.

The previous and next links are adaptive. For example, if you "View from page 361 for 3 pages" then your view will consist of 3 pages and the previous and next links will refer to the previous or next 3 pages.

You search a range of chapters or pages.

Search results are categorized by chapter, and the entire paragraph containing the query is displayed. That is, the query is applied per paragraph.

You can search using regular expressions (RE). The following PCRE meta-characters are supported:

\ . ? * + | [ ^ - ]

Do not enclose the RE in delimiters – the search engine will do that for you. Do not use \b for whole word and do not append an i for case-insensitivity – use the "whole word" and "case sensitive" checkbox options on the search form.

In addition to RE support the search engine supports three logical operators: NOT (!), AND (&&) and OR (||). It also supports parentheses for grouping. Some examples follow.

The following query will return all paragraphs (in the specified range) which have "Mind" AND have either "creat" OR "power".

Mind && (creat || power)

Note that the above query is much more efficient when written as follows, so that "creat|power" is written as an RE instead of using the logical OR (||) operator. You should do this when possible.

Mind && creat|power

The following is a case where the logical OR (||) operator is needed.

Principle && ((Mind && Spirit && Soul) || (Life && Truth && Love))

Everything between logical operators (and the beginning and end of the query) is parsed as an RE but has leading and trailing spaces removed. Spaces within the RE are not removed. For example, in the following the REs are "Spirit", "the only" and "sub".

Spirit && the only && sub

In the flow of HTML, marginal headings and page:line references precede their paragraph. When you copy-n-paste, headings and references will be on their own lines, preceding their associated text. To include the marginal heading when you select (click and drag across) a paragraph, start the selection at the end of the last sentence in the previous paragraph.

When viewing by chapter note that the Preface is chapter 0 (zero) for S&H-1910.

'Page:Line' references are in the left margin. A reference will be used at (1) the first line of a page (465:1); and (2) the first line of a paragraph (575:7). In the search results, the page:line references are links.

If "flowing lines" is unchecked, lines are wrapped exactly as in the print version of the book. If "flowing lines" is checked, lines are not wrapped – sentences in a paragraph will flow together to fill the available width – and the first line of each paragraph is labeled with the correct page:line reference.
