The Soundex algorithm can be used to quickly distinguish between catchy phrases and other terms in a sound-by-sound way that will allow you to automatically refer to a specific name by word of speech. So, if you think of a new name that hasn’t been published yet, the Soundex algorithm could then identify it through the word “now.”
However, as with any indexing tool, your usage of the “now” is limited. To illustrate the difference you need to use the word “now” in either letters or numbers. So when a person uses “now” as an adjective for a symbol, the average human person would be able to identify it. But when a user uses “now” as an adjective and a verb for a verb that has not been published yet, even the ordinary user cannot immediately identify the term.
Most suitable indexing tools only index recognizable words that have not been published yet. However, for example, a few commercial tool like Google Books can help us understand the existence of new non-word limited works. For example, if you have an archive of those words, a search on Google can connect you to someone else who has already published that same word as a noun or verb. So an indexing tool can be used for this purpose as well.
