These are individual characters that convey meaning and are an important part of a word. Although only the numbers 0 through 9 appear in this field, the letters A to Z, in both upper and lower case, and the international character set are also considered significant and are automatically placed in this category. You may want to specify other characters to suit your purposes, for instance the dollar sign ($) if you need to search prices. For example, if the hyphen was made significant, then post-graduate would be indexed as post-graduate and a query for postgraduate would not return post-graduate and vice versa.
To add a new significant character, enter it into the Significant field. To delete a significant character simply delete it from the field.
Note: You must perform a Reindex for any changes made to significant characters to take effect.
These are individual characters which are part of a word but are not regarded as important. Insignificant characters are treated as if they are invisible. For instance if the hyphen is made insignificant, then words which are hyphenated will be treated as one word, for example post-graduate would be indexed as postgraduate.
The default insignificant characters are the apostrophe ('), single quote(' ') and underscore(_). To add a new insignificant character, enter it in the insignificant field. To delete an insignificant character simply delete it from the field.
Note: You must perform a Reindex for any changes made to insignificant characters to take effect.
Use this option to select the language that the documents to be indexed are written in. Selecting Korean, Chinese, Hong Kong Chinese or Japanese enables multi-byte character support during indexing. This will not change the language of the documents being indexed.
Setting this option indexes all characters as Unicode, using the encoding of the document where available (Formats that specify encoding include Microsoft Office formats and Adobe Acrobat files). For documents that do not specify their encoding, such as text files, the encoding set in the option above will be used.
This allows a single index to contain documents from multiple languages, e.g. French, Chinese, Russian and English in a single index.
Setting this option will lead to larger index file.
Note: You must perform a Reindex for any changes made to the index language to take effect.
